Constructor Detail

AbstractUpdateStatement

public AbstractUpdateStatement(SqlDialect dialect,
                               EntityAlias<E> alias)

The constructor.

Parameters:

dialect - - see AbstractStatement.getDialect().

alias - - see AbstractStatement.getAlias().

Method Detail

where

public SELF where(Expression... expressions)

Description copied from interface: FeatureWhere

Adds the given Expressions as filter criteria to the WHERE-clause. Multiple invocations will combine Expressions with logical AND but it is preferred to use a single invocation.

Specified by:

where in interface FeatureWhere<SELF extends UpdateStatement<E,SELF>>

Parameters:

expressions - the Expressions to add.

Returns:

this query instance for fluent API calls.

limit

public SELF limit(int limit)

Description copied from interface: FeatureLimit

Set the limit for the query matches. Should be called only once per query.

Specified by:

limit in interface FeatureLimit<SELF extends UpdateStatement<E,SELF>>

Parameters:

limit - the limit for the maximum number of matches for the query.

Returns:

this query instance for fluent API calls.

buildStart

protected void buildStart(SqlBuilder builder)

Overrides:

buildStart in class AbstractStatement<E,SELF extends UpdateStatement<E,SELF>>

Parameters:

builder - the SqlBuilder with the query context to build the SQL and bind variables.
