Method Detail

unparseOffsetFetch

public void unparseOffsetFetch(SqlWriter writer,
                               @Nullable SqlNode offset,
                               @Nullable SqlNode fetch)

Description copied from class: SqlDialect

Converts an offset and fetch into SQL.

At least one of offset and fetch must be provided.

Common options:

• OFFSET offset ROWS FETCH NEXT fetch ROWS ONLY (ANSI standard SQL, Oracle, PostgreSQL, and the default)
• LIMIT fetch OFFSET offset (Apache Hive, MySQL, Redshift)

Overrides:

unparseOffsetFetch in class SqlDialect

Parameters:

writer - Writer

offset - Number of rows to skip before emitting, or null

fetch - Number of rows to fetch, or null

See Also:

SqlDialect.unparseFetchUsingAnsi(SqlWriter, SqlNode, SqlNode), SqlDialect.unparseFetchUsingLimit(SqlWriter, SqlNode, SqlNode)

unparseTopN

public void unparseTopN(SqlWriter writer,
                        @Nullable SqlNode offset,
                        @Nullable SqlNode fetch)

Description copied from class: SqlDialect

Converts a fetch into a "SELECT TOP(fetch)".

A dialect that uses "TOP" syntax should override this method to print "TOP(fetch)", and override SqlDialect.unparseOffsetFetch(org.apache.calcite.sql.SqlWriter, org.apache.calcite.sql.SqlNode, org.apache.calcite.sql.SqlNode) to no-op.

The default implementation of this method is no-op.

Overrides:

unparseTopN in class SqlDialect

Parameters:

writer - Writer

offset - Number of rows to skip before emitting, or null

fetch - Number of rows to fetch, or null
