pg_result_error_field

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

pg_result_error_field — Devuelve un campo individual de un informe de error

Descripción

pg_result_error_field(PgSql\Result $result, int $field_code): string|false|null

pg_result_error_field() devuelve uno de los campos detallados del mensaje de error asociados al recurso result. Esta función está disponible solo en servidores PostgreSQL 7.4 o superiores. El campo de error se especifica mediante field_code.

Dado que pg_query() y pg_query_params() devuelven false si la consulta falla, se debe utilizar pg_send_query() y pg_get_result() para obtener el conjunto de resultados.

Si se necesita obtener más información sobre el error al fallar las consultas con pg_query(), se debe utilizar pg_set_error_verbosity() y pg_last_error() y analizar posteriormente el resultado.

Parámetros

result: An PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).
field_code: Los valores posibles de field_code son: PGSQL_DIAG_SEVERITY, PGSQL_DIAG_SQLSTATE, PGSQL_DIAG_MESSAGE_PRIMARY, PGSQL_DIAG_MESSAGE_DETAIL, PGSQL_DIAG_MESSAGE_HINT, PGSQL_DIAG_STATEMENT_POSITION, PGSQL_DIAG_INTERNAL_POSITION (solo PostgreSQL 8.0+), PGSQL_DIAG_INTERNAL_QUERY (solo PostgreSQL 8.0+), PGSQL_DIAG_CONTEXT, PGSQL_DIAG_SOURCE_FILE, PGSQL_DIAG_SOURCE_LINE o PGSQL_DIAG_SOURCE_FUNCTION.

Valores devueltos

Devuelve una cadena que contiene el contenido del campo de error, null si el campo no existe o false en caso de fallo.

Historial de cambios

Complete list of field codes from libpq documentation...

Warning : they are prefixed with "PG_", just change to "PGSQL_" and they'll be available as defined PHP values.

For me, most importants fields are suffixed with a star ;)
