Method Detail

processSql

public java.lang.String processSql(java.lang.String sql,
                                   RowSelection selection)

Description copied from interface: LimitHandler

Return processed SQL query.

Specified by:

processSql in interface LimitHandler

Overrides:

processSql in class AbstractLimitHandler

Parameters:

sql - the SQL query to process.

selection - the selection criteria for rows.

Returns:

Query statement with LIMIT clause applied.

bindLimitParametersAtStartOfQuery

public int bindLimitParametersAtStartOfQuery(RowSelection selection,
                                             java.sql.PreparedStatement statement,
                                             int index)

Description copied from interface: LimitHandler

Bind parameter values needed by the LIMIT clause before original SELECT statement.

Specified by:

bindLimitParametersAtStartOfQuery in interface LimitHandler

Overrides:

bindLimitParametersAtStartOfQuery in class AbstractLimitHandler

Parameters:

selection - the selection criteria for rows.

statement - Statement to which to bind limit parameter values.

index - Index from which to start binding.

Returns:

The number of parameter values bound.

bindLimitParametersAtEndOfQuery

public int bindLimitParametersAtEndOfQuery(RowSelection selection,
                                           java.sql.PreparedStatement statement,
                                           int index)

bindLimitParametersAtEndOfQuery in class AbstractLimitHandler

Parameters:

selection - the selection criteria for rows.

statement - Statement to which to bind limit parameter values.

index - Index from which to start binding.

Returns:

The number of parameter values bound.

setMaxRows

public void setMaxRows(RowSelection selection,
                       java.sql.PreparedStatement statement)
                throws java.sql.SQLException

Description copied from interface: LimitHandler

Use JDBC API to limit the number of rows returned by the SQL query. Typically handlers that do not support LIMIT clause should implement this method.

Specified by:

setMaxRows in interface LimitHandler

Overrides:

setMaxRows in class AbstractLimitHandler

Parameters:

selection - the selection criteria for rows.

statement - Statement which number of returned rows shall be limited.

Throws:
