db2_bind_param Binds a PHP variable to an SQL statement parameter &reftitle.description; booldb2_bind_param resourcestmt longparameter-number stringvariable-name longparameter-type longdata-type longprecision longscale &warn.experimental.func; Binds a PHP variable to an SQL statement parameter in a statement resource returned by db2_prepare. This function gives you more control over the parameter type, data type, precision, and scale for the parameter than simply passing the variable as part of the optional input array to db2_execute. &reftitle.parameters; stmt A prepared statement returned from db2_prepare. parameter-number Specifies the 1-indexed position of the parameter in the prepared statement. variable-name A string specifying the name of the PHP variable to bind to the parameter specified by parameter-number. parameter-type A constant specifying whether the PHP variable should be bound to the SQL parameter as an input parameter (DB2_PARAM_IN), an output parameter (DB2_PARAM_OUT), or as a parameter that accepts input and returns output (DB2_PARAM_INOUT). data-type A constant specifying the SQL data type that the PHP variable should be bound as: one of DB2_BINARY, DB2_CHAR, DB2_DOUBLE, or DB2_LONG . precision Specifies the precision with which the variable should be bound to the database. scale Specifies the scale with which the variable should be bound to the database. &reftitle.returnvalues; &return.success; &reftitle.examples; The SQL statement in the following example uses two input parameters in the WHERE clause. We call db2_bind_param to bind two PHP variables to the corresponding SQL parameters. Notice that the PHP variables do not have to be declared or assigned before the call to db2_bind_param; in the example, $lower_limit is assigned a value before the call to db2_bind_param, but $upper_limit is assigned a value after the call to db2_bind_param. The variables must be bound and, for parameters that accept input, must have any value assigned, before calling db2_execute. ?
