Pg_prepare Cannot Set Connection To Blocking Mode

For numeric values, you can either use a number or use a literal '$1'. If DBD::Pg is unable to figure out the version, it will return a "0". Examples: Not legal: $SQL = 'SELECT count(*) FROM pg_class WHERE relpages > $2'; # Does not start with 1 $SQL = 'SELECT count(*) FROM pg_class WHERE relpages BETWEEN $1 AND $3'; Common codes: 00000 Successful completion 25P01 No active SQL transaction 25P02 In failed SQL transaction S8006 Connection failure trace $h->trace($trace_settings); $h->trace($trace_settings, $trace_filename); $trace_settings = $h->trace; Changes the trace settings on a

The first case would be harmless, as your script would certainly notice the lost connection for later calls and react to that (or fail more noticeable). Try changing these lines: orig = PGG(ignore_notices); PGG(ignore_notices) = 1; res = PQexec(link,"BEGIN;"); PQclear(res); res = PQexec(link,"ROLLBACK;"); PQclear(res); PGG(ignore_notices) = orig; to this: if ((PQprotocolVersion(link) >= 3 && PQtransactionStatus(link) != PQTRANS_IDLE) In this instance, conn.exec returns the value of the block. static VALUE pgconn_lowrite(VALUE self, VALUE in_lo_desc, VALUE buffer) { int Home · Authors · Recent · News · Mirrors · FAQ · Feedback in All Modules Distributions Authors permalink Greg

Useful for statements that contain an array slice. The second execute will not, but will build the query into a single string and send it to the server. The read-only effect is accomplished by sending a SETTRANSACTIONREADONLY after every begin.

The $bind_value argument is fairly self-explanatory. pg_lo_export $ret = $dbh->pg_lo_export($lobjId, $filename); Exports a large object into a Unix file. share|improve this answer answered Oct 13 '09 at 20:31 Bill Karwin 285k51398572 1 +1 - I assumed that he is doing it asynchronously on purpose, given the 'long-running script' remark, static VALUE pgconn_loexport(VALUE self, VALUE lo_oid, VALUE filename) { PGconn *conn = pg_get_pgconn(self); Oid oid; Check_Type(filename, T_STRING); oid = NUM2UINT(lo_oid); if (lo_export(conn, oid, StringValueCStr(filename)) < 0) { rb_raise(rb_ePGerror, "%s", PQerrorMessage(conn)); }

selectrow_array @row_ary = $dbh->selectrow_array($sql); @row_ary = $dbh->selectrow_array($sql, \%attr); @row_ary = $dbh->selectrow_array($sql, \%attr, @bind_values); Returns an array of row information after preparing and executing the provided SQL string. To do this, there must be at least one column in the table with a NOT NULL constraint, that has a unique constraint, and which uses a sequence as a default This is the same as the DSN, without the "dbi:Pg:" part. http://mailman.nginx.org/pipermail/nginx/2016-June/050988.html Is this a known limitation or bug in nginx?

It would seem like it's wasting cpu cycles to start up a transaction and then rolling back the transactions doing nothing. This method is most useful when using a server that supports server-side prepares, and you have asked the prepare to happen immediately via the pg_prepare_now attribute. I'm looking at php 4.3.10 and I'm using postgres 8.0.1. parse_trace_flag and parse_trace_flags $h->trace($h->parse_trace_flags('SQL|pglibpq')); $h->trace($h->parse_trace_flags('1|pgstart')); ## Simpler: $h->trace('SQL|pglibpq'); $h->trace('1|pgstart'); my $value = DBD::Pg->parse_trace_flag('pglibpq'); DBI->trace($value); The parse_trace_flags method is used to convert one or more named flags to a number which can

You cannot send more than one command at a time in the same prepare command (by separating them with semi-colons) when using server-side prepares. For example: [zephyr] dbname=winds user=wisp password=W$2Hc00YSgP port=6543 There are four valid arguments to the sslmode parameter, which controls whether to use SSL to connect to the database: disable: SSL connections are The PG team have apparently solved this issue, so I've dropped persistence as it was cluttering up my system unnecessarily. Consider this a safety net to catch applications that should not be issuing commands such as INSERT, UPDATE, or DELETE.

Example with CSV input format: conn.exec "create table my_table (a text,b text,c text,d text)" conn.copy_data "COPY my_table FROM STDIN CSV" do conn.put_copy_data "some,data,to,copy\n" conn.put_copy_data "more,data,to,copy\n" end This creates my_table and inserts The list is in primary key column sequence order. If the value contains backslashes, and the server is version 8.1 or higher, then the escaped string syntax will be used (which places a capital E before the first single quote). PGG(ignore_notices) && Z_TYPE_P(return_value) == IS_RESOURCE) { PQsetNoticeProcessor(pgsql, _php_pgsql_notice_handler, (void*)Z_RESVAL_P(return_value)); } php_pgsql_set_default_link(Z_LVAL_P(return_value) TSRMLS_CC); cleanup: smart_str_free(&str); return; err: smart_str_free(&str); RETURN_FALSE; } /* }}} */ #if 0 /* {{{ php_pgsql_get_default_link */ static int php_pgsql_get_default_link(INTERNAL_FUNCTION_PARAMETERS)

table_info $sth = $dbh->table_info(undef, $schema, $table, $type); Returns all tables and views visible to the current user. pg_placeholder_nocolons (boolean) DBD::Pg specific attribute. Note that 0 is a perfectly correct (and common) object descriptor! Is this a known limitation or bug in nginx?

This is especially important when using server-side prepares.

This information is also output if the trace level is set to 4 or greater.

pg_send_prepare() - async equivalent of pg_prepare(). . This attribute is on by default. A value of 0 indicates no error (CONNECTION_OK), while any other number indicates a failed connection. Try to update PHP to the latest version - maybe this is a bug in PHP and it is already fixed.

Sometimes we see erros like this: 2016/06/14 12:47:23 [error] 31450#31450: *177931 FastCGI sent in stderr: "PHP message: PHP Notice: pg_execute(): Cannot set connection to blocking mode in /data/example.com/vendor/zendframework/zend-db/src/Adapter/Driver/Pgsql/Statement.php on line 228 You can also connect by using a service connection file, which is named pg_service.conf. pglogin Outputs a message showing the connection string right before a new database connection is attempted, a message when the connection was successful, and a message right after the database has static VALUE pgconn_describe_portal(self, stmt_name) VALUE self, stmt_name; { PGresult *result; VALUE rb_pgresult; PGconn *conn = pg_get_pgconn(self); const char *stmt; if(NIL_P(stmt_name)) { stmt = NULL; } else { stmt = pg_cstr_enc(stmt_name, ENCODING_GET(self));

The prepare method prepares a statement for later execution. HandleSetErr (code ref, inherited) Implemented by DBI, no driver-specific impact. This is a number used by libpq and is one of: 0 Empty query string 1 A command that returns no data successfully completed. 2 A command that returns data successfully Will be one of "TABLE", "VIEW", "MATERIALIZED VIEW", "SYSTEM VIEW", "SYSTEM MATERIALIZED VIEW", "SYSTEM TABLE", or "LOCAL TEMPORARY".
