Can not load PosgreSQL client. Is it installed? (libpq.so)
solving:
create link for libpq.
$ cd /usr/lib
$ sudo ln -s libpq.so.5.1 libpq.so
Lazarus and Postgresql connection
Component needed:
- PQConnection (SQLdb Tab)
- TSQLTransaction (SQLdb Tab)
- TSQLQuery (SQLdb Tab)
- TDataSource (Data Access Tab)
- TDBGrid (Data Control Tab)
In PQConnection
set databasename, hostname, username, password
In TSQLTransaction
set database to PQConnection object
In SQLQuery
set database to PQConnection object
set transaction to TSQLTransaction object
keep DataSource blank
In TDataSource
set DataSet to SQLQuery object
In TDBGrid
set DataSource to TDataSource object
Then, activate all
