db2_exec Executes an SQL statement directly &reftitle.description; resourcedb2_exec resourceconnection stringstatement arrayoptions Prepares and executes an SQL statement. If you plan to interpolate PHP variables into the SQL statement, understand that this is one of the more common security exposures. Consider calling db2_prepare to prepare an SQL statement with parameter markers for input values. Then you can call db2_execute to pass in the input values and avoid SQL injection attacks. If you plan to repeatedly issue the same SQL statement with different parameters, consider calling db2_prepare and db2_execute to enable the database server to reuse its access plan and increase the efficiency of your database access. &reftitle.parameters; connection A valid database connection resource variable as returned from db2_connect or db2_pconnect. statement An SQL statement. The statement cannot contain any parameter markers. options An associative array containing statement options. You can use this parameter to request a scrollable cursor on database servers that support this functionality. cursor Passing the DB2_FORWARD_ONLY value requests a forward-only cursor for this SQL statement. This is the default type of cursor, and it is supported by all database servers. It is also much faster than a scrollable cursor. Passing the DB2_SCROLLABLE value requests a scrollable cursor for this SQL statement. This type of cursor enables you to fetch rows non-sequentially from the database server. However, it is only supported by DB2 servers, and is much slower than forward-only cursors. &reftitle.returnvalues; Returns a statement resource if the SQL statement was issued successfully, or &false; if the database failed to execute the SQL statement. &reftitle.examples; The following example uses db2_exec to issue a set of DDL statements in the process of creating a table. ]]> &example.outputs; The following example demonstrates how to request a scrollable cursor for an SQL statement issued by db2_exec.
