# PDOSQLExecTask¶

Executes a series of SQL statements on a database using PDO.

<p>Statements can either be read in from a text file using the <i>src</i> attribute or from between the enclosing SQL tags.</p> <p>Multiple statements can be provided, separated by semicolons (or the defined <i>delimiter</i>). Individual lines within the statements can be commented using either --, // or REM at the start of the line.</p> <p>The <i>autocommit</i> attribute specifies whether auto-commit should be turned on or off whilst executing the statements. If auto-commit is turned on each statement will be executed and committed. If it is turned off the statements will all be executed as one transaction.</p> <p>The <i>onerror</i> attribute specifies how to proceed when an error occurs during the execution of one of the statements. The possible values are: <b>continue</b> execution, only show the error; <b>stop</b> execution and commit transaction; and <b>abort</b> execution and transaction and fail task.</p>

# PgsqlPDOQuerySplitter¶

Splits PostgreSQL's dialect of SQL into separate queries

Unlike DefaultPDOQuerySplitter this uses a lexer instead of regular expressions. This allows handling complex constructs like C-style comments (including nested ones) and dollar-quoted strings.
