pg_insert

    (PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

    pg_insert — Insert array into table

    Descrição

    pg_insert(
        PgSql\Connection$connection,
        string$table_name,
        array$values,
        int$flags = PGSQL_DML_EXEC
    ): PgSql\Result|string|bool

    pg_insert() inserts the values of values into the table specified by table_name.

    If flags is specified, pg_convert() is applied to values with the specified flags.

    By default pg_insert() passes raw values. Values must be escaped or the PGSQL_DML_ESCAPE flag must be specified in flags. PGSQL_DML_ESCAPE quotes and escapes parameters/identifiers. Therefore, table/column names become case sensitive.

    Note that neither escape nor prepared query can protect LIKE query, JSON, Array, Regex, etc. These parameters should be handled according to their contexts. i.e. Escape/validate values.

    Parâmetros

    connection

    Uma instância de PgSql\Connection.

    table_name

    Name of the table into which to insert rows. The table table_name must at least have as many columns as values has elements.

    values

    An array whose keys are field names in the table table_name, and whose values are the values of those fields that are to be inserted.

    flags

    Any number of PGSQL_CONV_OPTS, PGSQL_DML_NO_CONV, PGSQL_DML_ESCAPE, PGSQL_DML_EXEC, PGSQL_DML_ASYNC or PGSQL_DML_STRING combined. If PGSQL_DML_STRING is part of the flags then query string is returned. When PGSQL_DML_NO_CONV or PGSQL_DML_ESCAPE is set, it does not call pg_convert() internally.

    Valor Retornado

    Retorna true em caso de sucesso ou false em caso de falha.. Or returns a string on success if PGSQL_DML_STRING is passed via flags.

    Erros/Exceções

    A ValueError is thrown when the specified table is invalid.

    A ValueError or TypeError is thrown when the value or type of field does not match properly with a PostgreSQL's type.
