## 例

`

     string pg_escape_literal ([ resource $connection ], string $data )

`

## 説明

pg_escape_literal() escapes a literal for querying the PostgreSQL database. It returns an escaped literal in the PostgreSQL format. pg_escape_literal() adds quotes before and after data. Users should not add quotes. Use of this function is recommended instead of pg_escape_string(). If the type of the column is bytea, pg_escape_bytea() must be used instead. For escaping identifiers (e.g. table, field names), pg_escape_identifier() must be used. Note: This function has internal escape code and can also be used with PostgreSQL 8.4 or less.

## 戻り値

A string containing the escaped data.
