Normally, you would use the higher-level SQLDB code as it allows you to code more quickly, easily switch databases etc.

INSERT INTO films ( film_name ) VALUES ( 'val' ) RETURNING id, 'a' AS a, id * 2 AS doubled_id, CASE WHEN id > 100 THEN 'a' ELSE 'b' END AS foo PostgreSQL package: the low level unitsĪs with all databases, the SQLDB code depends on a lower level PostgreSQL specific unit that wraps around the PostgreSQL driver library (.so/.dll/.dylib).
POSTGRES ADD TO PATH OSX 64 BIT
If you are developing 64 bit applications, you must use a 64 bit DLL. lib/something/ in your project directory, and the project directory
or (Windows) to the program output directory (e.g. to a directory in the (library search) path (e.g. It is a thin wrapper around FPC PQEventMonitor please see the FPC pqeventstest.pp example programs for details.Īs with all sqldb units, you need to add your driver libraries ( all required PostgreSQL. If you have FPC2.6.2+ and a recent version of Lazarus, you can use the TPQTEventMonitor component to monitor events coming from PostgreSQL. See SQLdb_Tutorial1 for a tutorial on creating a GUI database-enabled program that is written for PostgreSQL/SQLDB, as well as SQLite/SQLDB, Firebird/SQLDB, basically any RDBMS SQLDB supports). Add ( 'application_name= '' yourappname '' ' )įor all supported connection parameters see: Connection Parameter Key Words Example The TPQConnection component does not directly support a Port property, but one can pass the port into the component via the Params parameter: The CharSet property is used for client encoding. Library once at the start of the process with the InitialisePostgres3 call. To prevent this from happening (and speed up the application), you can load the This means that whenever the lastĬonnection is closed, a small memory leak is created. SQLDB loads the library when the first connection is made, and unloads it when the last connection closes. Note: The libpq C client contains some memory leaks (at least up till version 9.3 of Postgres) when a library is repeatedly loaded/unloaded. If you are using FPC only or want to manually add PostgreSQL support, add pqconnection to your uses clause. Zeos supports PostgreSQL please see ZeosDBO SQLDBįPC/Lazarus supports PostgreSQL out of the box with a PostgreSQL connection component/class. You can download this Lazarus component for free. PgDAC is designed to help programmers develop really lightweight, faster and cleaner PostgreSQL database applications without deploying any additional libraries. POSTGRES ADD TO PATH OSX MAC OS
It is a library of components that provides native connectivity to PostgreSQL from Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. You can connect Lazarus with PostgreSQL by using PostgreSQL Data Access Components (PgDAC). Win64: please see warning here on not using certain FPC/Lazarus Win64 versions.
Liberal license (no costs) in comparison with MySQL. Very stable and has a complete feature set. If you are looking for information on the postgres package in FPC, please see postgres#PostgreSQL_package:_the_low_level_units below. You can use Free Pascal/Lazarus to access a PostgreSQL database server. 6 PostgreSQL package: the low level units. 5.1.2 Get multiple fields and expressions. 4.3.2 Error: "Can not load PostgreSQL client library "libpq.dll"". Once you've found it, find the lines in postgresql. This link is quite old but it may put you on the right track if you're having trouble. You may need to spend some time on google. That in itself could be difficult, I'm a linux user not OSX. Track down the main configuration file for postgres ( nf). The socket file itself is created by postgresql when it starts up. 
It's likely that you do already have access to this and it's just the socket file you don't have permission to. This will result in "permission denied" if not. On the command line use: ls -l /var/pgsql_socket/.s.PGSQL.5432 You don't have access to the ("socket") file /var/pgsql_socket/.s.PGSQL.5432Ĭheck that you at least have access to the directory.
This error is pretty specific and tells you what is wrong, but if you're new to unix then it's less obvious.
