ODBC_SQLSetStmtAttr ( stmtID ; attribute ; valuePtr ) -> Function result

Parameter	Type	Description
stmtID	Longint	Statement ID
attribute	Longint	Attribute to set
valuePtr	Pointer	Pointer to the value to set the attribute
Function result	Longint	Returns the result of the MS ODBC API function SQLSetStmtAttr

Description

The ODBC_SQLSetStmtAttr command sets attribute related to a statement.

stmtID is a valid statement ID returned by ODBC_SQLAllocStmt.

attribute is a statement attribute to set and can be one of the following values:

Constant	Description
SQL_ATTR_APP_PARAM_DESC
SQL_ATTR_APP_ROW_DESC
SQL_ATTR_ASYNC_ENABLE	Specifies whether a function called with the specified statement is executed asynchronously
SQL_ATTR_CONCURRENCY	Specifies the cursor concurrency
SQL_ATTR_CURSOR_SCROLLABLE	Scrollable cursors are either required or not required for the specified statement
SQL_ATTR_CURSOR_SENSITIVITY	Specifies whether cursors for the specified statement handle make visible the changes made to a result set by another cursor
SQL_ATTR_CURSOR_TYPE	Specifies cursor type, like scrolls forward, static, saves and uses the keys for the number of specified rows specified or only those in the row set
SQL_ATTR_ENABLE_AUTO_IPD	SQL_TRUE = Turns on automatic population of the IPD after a call to ODBC_SQLPrepare. SQL_FALSE = Turns off automatic population of the IPD after a call to ODBC_SQLPrepare.
SQL_ATTR_FETCH_BOOKMARK_PTR	Bookmark value
SQL_ATTR_IMP_PARAM_DESC	The value of this attribute is the descriptor allocated when the statement was initially allocated.
SQL_ATTR_IMP_ROW_DESC	The value of this attribute is the descriptor allocated when the statement was initially allocated.
SQL_ATTR_KEYSET_SIZE	Number of rows in the keyset for a keyset-driven cursor
SQL_ATTR_MAX_LENGTH	Maximum amount of data that the driver returns from a character or binary column.
SQL_ATTR_MAX_ROWS	Maximum number of rows to return to the application for a SELECT statement.
SQL_ATTR_METADATA_ID	Determines how the string arguments of catalog functions are treated.
SQL_ATTR_NOSCAN	Indicates whether the driver should scan SQL strings for escape sequences.
SQL_ATTR_PARAM_BIND_OFFSET_PTR	Bind offset.
SQL_ATTR_PARAM_BIND_TYPE	Indicates the binding orientation to be used for dynamic parameters.
SQL_ATTR_PARAM_OPERATION_PTR	Indicates if a parameter is to be ignored during execution of an SQL statement.
SQL_ATTR_PARAM_STATUS_PTR	Status information for each row of parameter values.
SQL_ATTR_PARAMS_PROCESSED_PTR	Number of sets of parameters that have been processed, including error sets.
SQL_ATTR_PARAMSET_SIZE	Specifies the number of values for each parameter.
SQL_ATTR_QUERY_TIMEOUT	Number of seconds to wait for an SQL statement to execute.
SQL_ATTR_RETRIEVE_DATA	Either retrieve or do not retrieve data after it positions the cursor to the specified location.
SQL_ATTR_ROW_ARRAY_SIZE	Number of rows returned by each call to ODBC_SQLFetch or ODBC_SQLFetchScroll
SQL_ATTR_ROW_BIND_OFFSET_PTR	An offset to change binding of column data.
SQL_ATTR_ROW_BIND_TYPE	The binding orientation to be used when ODBC_SQLFetch or ODBC_SQLFetchScroll is called on the specified statement.
SQL_ATTR_ROW_NUMBER	Number of the current row in the entire result set.
SQL_ATTR_ROW_OPERATION_PTR	Values used to ignore a row during a bulk operation using ODBC_SQLSetPos.
SQL_ATTR_ROW_STATUS_PTR	Row status values after a call to ODBC_SQLFetchor ODBC_SQLFetchScroll.
SQL_ATTR_ROWS_FETCHED_PTR	Number of rows fetched after a call to ODBC_SQLFetch or ODBC_SQLFetchScroll.
SQL_ATTR_SIMULATE_CURSOR	Specifies whether drivers that simulate positioned update and delete statements guarantee that such statements affect only one single row.
SQL_ATTR_USE_BOOKMARKS	Specifies whether an application will use bookmarks with a cursor.

valuePtr is a pointer to a variable containing the value at which to set the attribute parameter.
