Make sure you have an odbc.ini file in place, by which you can configure your DSN entries. A sample odbc.ini file is generated by the build process under the test folder. Set the environment variable ODBCINI to the location of your odbc.ini file. Set up a test DSN in your odbc.ini file (see Section 5.5, “Configuring a Connector/ODBC DSN on Unix” for details ).

4.5 Building Connector/ODBC from a Source Distribution on Unix
You need the following tools to build MySQL from source on Unix:
Once you have all the required files, unpack the source files to a separate directory, then run cmake with the following command:
Typical cmake Parameters and Options
You might need to help cmake find the MySQL headers and libraries by setting the environment variables
MYSQL_INCLUDE_DIR , MYSQL_LIB_DIR , and MYSQL_DIR to the appropriate locations; for example:
When you run cmake, you might add options to the command line. Here are some examples:
Build Steps for Unix
To build the driver libraries, execute make:
If any errors occur, correct them and continue with the build process. If you are not able to finish the build, see Section 9.1, “Connector/ODBC Community Support”.
Installing Driver Libraries
To install the driver libraries, execute the following command:
For more information on build process, refer to the
BUILD file that comes with the source distribution.

Summary
SQLDriverConnect is an alternative to SQLConnect. It supports data sources that require more connection information than the three arguments in SQLConnect, dialog boxes to prompt the user for all connection information, and data sources that are not defined in the system information.
SQLDriverConnect provides the following connection attributes:
After a connection is established, SQLDriverConnect returns the completed connection string. The application can use this string for subsequent connection requests. For more information, see Connecting with SQLDriverConnect.
SyntaxArguments
ConnectionHandle
[Input] Connection handle.
WindowHandle
[Input] Window handle. The application can pass the handle of the parent window, if applicable, or a null pointer if either the window handle is not applicable or SQLDriverConnect will not present any dialog boxes.
InConnectionString
[Input] A full connection string (see the syntax in 'Comments'), a partial connection string, or an empty string.
StringLength1
[Input] Length of *InConnectionString, in characters if the string is Unicode, or bytes if string is ANSI or DBCS.
OutConnectionString
[Output] Pointer to a buffer for the completed connection string. Upon successful connection to the target data source, this buffer contains the completed connection string. Applications should allocate at least 1,024 characters for this buffer.
If OutConnectionString is NULL, StringLength2Ptr will still return the total number of characters (excluding the null-termination character for character data) available to return in the buffer pointed to by OutConnectionString.
BufferLength
[Input] Length of the *OutConnectionString buffer, in characters.
StringLength2Ptr
[Output] Pointer to a buffer in which to return the total number of characters (excluding the null-termination character) available to return in *OutConnectionString. If the number of characters available to return is greater than or equal to BufferLength, the completed connection string in *OutConnectionString is truncated to BufferLength minus the length of a null-termination character.
DriverCompletion
[Input] Flag that indicates whether the Driver Manager or driver must prompt for more connection information:
SQL_DRIVER_PROMPT, SQL_DRIVER_COMPLETE, SQL_DRIVER_COMPLETE_REQUIRED, or SQL_DRIVER_NOPROMPT.
(For additional information, see 'Comments.')
Returns
SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_NO_DATA, SQL_ERROR, SQL_INVALID_HANDLE, or SQL_STILL_EXECUTING.
Diagnostics
When SQLDriverConnect returns either SQL_ERROR or SQL_SUCCESS_WITH_INFO, an associated SQLSTATE value may be obtained by calling SQLGetDiagRec with an fHandleType of SQL_HANDLE_DBC and an hHandle of ConnectionHandle. The following table lists the SQLSTATE values commonly returned by SQLDriverConnect and explains each one in the context of this function; the notation '(DM)' precedes the descriptions of SQLSTATEs returned by the Driver Manager. The return code associated with each SQLSTATE value is SQL_ERROR, unless noted otherwise.

A connection string has the following syntax:
connection-string ::= empty-string[;] | attribute[;] | attribute; connection-string
empty-string ::=attribute ::= attribute-keyword=attribute-value | DRIVER=[{]attribute-value[}]
attribute-keyword ::= DSN | UID | PWD | driver-defined-attribute-keyword
attribute-value ::= character-string
driver-defined-attribute-keyword ::= identifier
where character-string has zero or more characters; identifier has one or more characters; attribute-keyword is not case-sensitive; attribute-value may be case-sensitive; and the value of the DSN keyword does not consist solely of blanks.
Because of connection string and initialization file grammar, keywords and attribute values that contain the characters []{}(),;?*=!@ not enclosed with braces should be avoided. The value of the DSN keyword cannot consist only of blanks and should not contain leading blanks. Because of the grammar of the system information, keywords and data source names cannot contain the backslash () character.
Applications do not have to add braces around the attribute value after the DRIVER keyword unless the attribute contains a semicolon (;), in which case the braces are required. If the attribute value that the driver receives includes braces, the driver should not remove them but they should be part of the returned connection string.
A DSN or connection string value enclosed with braces ({}) containing any of the characters []{}(),;?*=!@ is passed intact to the driver. However, when using these characters in a keyword, the Driver Manager returns an error when working with file DSNs but passes the connection string to the driver for regular connection strings. Avoid using embedded braces in a keyword value.
![]()
The connection string may include any number of driver-defined keywords. Because the DRIVER keyword does not use information from the system information, the driver must define enough keywords so that a driver can connect to a data source using only the information in the connection string. (For more information, see 'Driver Guidelines,' later in this section.) The driver defines which keywords are required to connect to the data source.
The following table describes the attribute values of the DSN, FILEDSN, DRIVER, UID, PWD, and SAVEFILE keywords.
For information about how an application chooses a data source or driver, see Choosing a Data Source or Driver.
If any keywords are repeated in the connection string, the driver uses the value associated with the first occurrence of the keyword. If the DSN and DRIVER keywords are included in the same connection string, the Driver Manager and the driver use whichever keyword appears first.
The FILEDSN and DSN keywords are mutually exclusive: whichever keyword appears first is used, and the one that appears second is ignored. The FILEDSN and DRIVER keywords, on the other hand, are not mutually exclusive. If any keyword appears in a connection string with FILEDSN, then the attribute value of the keyword in the connection string is used rather than the attribute value of the same keyword in the .dsn file.
If the FILEDSN keyword is used, the keywords specified in a .dsn file are used to create a connection string. (For more information, see 'File Data Sources,' later in this section.) The UID keyword is optional; a .dsn file may be created with only the DRIVER keyword. The PWD keyword is not stored in a .dsn file. The default directory for saving and loading a .dsn file will be a combination of the path specified by CommonFileDir in HKEY_LOCAL_MACHINESOFTWAREMicrosoft WindowsCurrentVersion and 'ODBCDataSources'. (If CommonFileDir were 'C:Program FilesCommon Files', the default directory would be 'C:Program FilesCommon FilesODBCData Sources'.)
Note
A .dsn file can be manipulated directly by calling the SQLReadFileDSN and SQLWriteFileDSN functions in the installer DLL.
If the SAVEFILE keyword is used, the attribute values of keywords used in making the present, successful connection will be saved as a .dsn file with the name of the attribute value of the SAVEFILE keyword. The SAVEFILE keyword must be used in conjunction with the DRIVER keyword, the FILEDSN keyword, or both, or the function returns SQL_SUCCESS_WITH_INFO with SQLSTATE 01S09 (Invalid keyword). The SAVEFILE keyword must appear before the DRIVER keyword in the connection string, or the results will be undefined.
Driver Manager Guidelines
The Driver Manager constructs a connection string to pass to the driver in the InConnectionString argument of the driver's SQLDriverConnect function. The Driver Manager does not modify the InConnectionString argument passed to it by the application.
The action of the Driver Manager is based on the value of the DriverCompletion argument:
Drawing Operation Was Attempted Dev C 2017
If the connection string specified by the application contains the DRIVER keyword, the Driver Manager copies the connection string specified by the application.
Using the connection string it has constructed, the Driver Manager determines which driver to use, connects to that driver, and passes the connection string it has constructed to the driver; for more information about the interaction of the Driver Manager and the driver, see the 'Comments' section in SQLConnect Function. If the connection string does not contain the DRIVER keyword, the Driver Manager determines which driver to use as follows: Dane cook isolated incident mp3 download video.
File Data Sources
If the connection string specified by the application in the call to SQLDriverConnect contains the FILEDSN keyword, and this keyword is not superseded by either the DSN or DRIVER keyword, then the Driver Manager creates a connection string using the information in the .dsn file and the InConnectionString argument. The Driver Manager proceeds as follows:
For examples of .dsn files, see Connecting Using File Data Sources.
SAVEFILE Keyword
If the connection string specified by the application contains the SAVEFILE keyword, then the Driver Manager saves the connection string in a .dsn file. The Driver Manager proceeds as follows:
Driver Guidelines
The driver checks whether the connection string passed to it by the Driver Manager contains the DSN or DRIVER keyword. If the connection string contains the DRIVER keyword, the driver cannot retrieve information about the data source from the system information. If the connection string contains the DSN keyword or does not contain either the DSN or the DRIVER keyword, the driver can retrieve information about the data source from the system information as follows:
The driver uses any information it retrieves from the system information to augment the information passed to it in the connection string. If the information in the system information duplicates information in the connection string, the driver uses the information in the connection string.
Based on the value of DriverCompletion, the driver prompts the user for connection information, such as the user ID and password, and connects to the data source:
On successful connection to the data source, the driver also sets *StringLength2Ptr to the length of the output connection string that is available to return in *OutConnectionString.
If the user cancels a dialog box presented by the Driver Manager or the driver, SQLDriverConnect returns SQL_NO_DATA.
For information about how the Driver Manager and the driver interact during the connection process, see SQLConnect Function.
If a driver supports SQLDriverConnect, the driver keyword section of the system information for the driver must contain the ConnectFunctions keyword with the second character set to 'Y'.
Connecting When Connection Pooling Is Enabled
Connection pooling allows an application to reuse a connection that has already been created. When SQLDriverConnect is called, the Driver Manager attempts to make the connection using a connection that is part of a pool of connections in an environment that has been designated for connection pooling. For more information on connection pooling, see SQLConnect Function.
An application can set SQL_ATTR_RESET_CONNECTION before calling SQLDisconnect on a connection where pooling is enabled. For more information, see SQLSetConnectAttr Function.
The following restrictions apply when an application calls SQLDriverConnect to connect to a pooled connection:
Connection Attributes
The SQL_ATTR_LOGIN_TIMEOUT connection attribute, set using SQLSetConnectAttr, defines the number of seconds to wait for a login request to complete with a successful connection by the driver before returning to the application. If the user is prompted to complete the connection string, a waiting period for each login request begins when the driver starts the connection process.
The driver opens the connection in SQL_MODE_READ_WRITE access mode by default. To set the access mode to SQL_MODE_READ_ONLY, the application must call SQLSetConnectAttr with the SQL_ATTR_ACCESS_MODE attribute prior to calling SQLDriverConnect.
If a default translation library is specified in the system information for the data source, the driver loads it. A different translation library can be loaded by calling SQLSetConnectAttr with the SQL_ATTR_TRANSLATE_LIB attribute. A translation option can be specified by calling SQLSetConnectAttr with the SQL_ATTR_TRANSLATE_OPTION option.
