CA_API UINT __stdcall ODBC_Execute ( MSIHANDLE  hInstall)

Execute a SQL query, no result set.

Parameters
ODBC_CONNECTION_STRINGConnection string.
ODBC_SQL_QUERYQuery to execute.
ODBC_SQL_DELIMITERBatch delimiter. The contents of the SQL file will be split and executed one-by-one. Delimiter is case-insensitive, recognized only at the beginning of line. Either Type or Delimiter may be specified, not both.
ODBC_SQL_TYPEType of the sql script (SqlServer, Oracle, ...). This will set appropriate delimiters for sql splitting, e.g. 'go' for SqlServer; also.will provide support for insertion commands, e.g. ':r' for SqlServer.
Returns
ODBC_SQL_MESSAGES SQL execution messages, if available.

This custom action supports impersonation, see Impersonation in Immediate Custom Actions.

CA_API UINT __stdcall ODBC_Execute_Binary ( MSIHANDLE  hInstall)

Execute a SQL file stored as a binary object, no result set.

Parameters
ODBC_CONNECTION_STRINGConnection string.
ODBC_SQL_PROPERTYNAMEThe name of the Binary property that contains the SQL.
ODBC_SQL_DELIMITERBatch delimiter. The contents of the SQL file will be split and executed one-by-one. Delimiter is case-insensitive, recognized only at the beginning of line. Either Type or Delimiter may be specified, not both.
ODBC_SQL_TYPEType of the sql script (SqlServer, Oracle, ...). This will set appropriate delimiters for sql splitting, e.g. 'go' for SqlServer; also.will provide support for insertion commands, e.g. ':r' for SqlServer.
Returns
ODBC_SQL_MESSAGES SQL execution messages, if available.

Returns
ODBC_SQL_RESULT The returned scalar.

This custom action supports impersonation, see Impersonation in Immediate Custom Actions.

CA_API UINT __stdcall ODBC_GetString ( MSIHANDLE  hInstall)

Execute a SQL query, return a string.

Parameters
ODBC_CONNECTION_STRINGConnection string.
ODBC_SQL_QUERYQuery to execute.
ODBC_SQL_FLAGSOptional, possible flags are: ODBC_SQL_FLAG_NO_ROWS_RETURN_EMPTY
Returns

Example: Implementing "Recommend Path" with Microsoft SQL Server

Sometimes your application needs to prompt the user for a specific directory where a database should be installed. Most of the time the users want to install the database in the default SQL Server directory. This value is stored in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.1\Setup on the server and can be obtained with the the following T-SQL.

DECLARE @data_dir varchar(500)
EXECUTE master.dbo.xp_instance_regread 'HKEY_LOCAL_MACHINE', 'SOFTWARE\Microsoft\MSSQLServer\Setup', 'SQLDataRoot', @param = @data_dir OUTPUT
SELECT @data_dir

The query can be easily incorporated under a "Recommend Path" button in a wix UI using the ODBC_GetString custom action.

CA_API UINT __stdcall ODBC_GetXml ( MSIHANDLE  hInstall)

Execute a SQL query, return xml data set.

Parameters
ODBC_CONNECTION_STRINGConnection string.
ODBC_SQL_QUERYQuery to execute.
Returns
ODBC_SQL_RESULT The returned data set, in xml format.

The xml data returned looks like this:

<Data columns="number of columns" rows="number of rows">
<Query>query executed</Query>
<DataSet>
<Row>
<column1>value of column 1</column1>
<column2>value of column 2</column2>
...
</Row>
<Row>
...
</Row>
</DataSet>
</Data>
