Prepared statement

[2] On the other hand, if a query is executed only once, server-side prepared statements can be slower because of the additional round-trip to the server.

[3] Implementation limitations may also lead to performance penalties; for example, some versions of MySQL did not cache results of prepared queries.

Major DBMSs, including SQLite,[5] MySQL,[6] Oracle,[7] IBM Db2,[8] Microsoft SQL Server[9] and PostgreSQL[10] support prepared statements.

[11] A number of programming languages support prepared statements in their standard libraries and will emulate them on the client side even if the underlying DBMS does not support them, including Java's JDBC,[12] Perl's DBI,[13] PHP's PDO[1] and Python's DB-API.

Many types of SQL injection attacks can be eliminated by disabling literals, effectively requiring the use of prepared statements; as of 2007[update] only H2 supports this feature.

This example uses Python and DB-API: This example uses Direct SQL from Fourth generation language like eDeveloper, uniPaaS and magic XPA from Magic Software Enterprises PureBasic (since v5.40 LTS) can manage 7 types of link with the following commands There are 2 different methods depending on the type of database For SQLite, ODBC, MariaDB/Mysql use: ?
