pg_insert inserts the values
of assoc_array into the table specified
by table_name. If options
is specified, pg_convert is applied
to assoc_array with the specified options.
If options is specified,
pg_convert is applied to
assoc_array with the specified flags.
By default pg_insert passes raw values. Values
must be escaped or PGSQL_DML_ESCAPE option must be
specified. PGSQL_DML_ESCAPE quotes and escapes
paramters/identifiers. Therefore, table/column names became 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.
&reftitle.parameters;
connection
PostgreSQL database connection resource.
table_name
Name of the table into which to insert rows. The table table_name must at least
have as many columns as assoc_array has elements.
assoc_array
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.
options
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
options then query string is returned. When PGSQL_DML_NO_CONV
or PGSQL_DML_ESCAPE is set, it does not call pg_convert internally.
&reftitle.returnvalues;
Returns the connection resource on success, &return.falseforfailure;. Returns string if PGSQL_DML_STRING is passed
via options.
