pg_execute
Sends a request to execute a prepared statement with given parameters, and waits for the result.
pg_execute is like pg_query_params, but the command to be executed is specified by naming a previously-prepared statement, instead of giving a query string. This feature allows commands that will be used repeatedly to be parsed and planned just once, rather than each time they are executed. The statement must have been prepared previously in the current session. pg_execute is supported only against PostgreSQL 7.4 or higher connections; it will fail when using earlier versions.
The parameters are identical to pg_query_params, except that the name of a prepared statement is given instead of a query string.
Parameters
- connection
-
An PgSql\Connection instance. When connection is unspecified, the default connection is used. The default connection is the last connection made by pg_connect or pg_pconnect.
Warning:
As of PHP 8.1.0, using the default connection is deprecated.
- stmtname
-
The name of the prepared statement to execute. if "" is specified, then the unnamed statement is executed. The name must have been previously prepared using pg_prepare, pg_send_prepare or a PREPARE SQL command.
- params
-
An array of parameter values to substitute for the $1, $2, etc. placeholders in the original prepared query string. The number of elements in the array must match the number of placeholders.
Warning:
Elements are converted to strings by calling this function.
Return Values
An PgSql\Result instance on success, or false on failure.
