Create a SQL JOIN clause based on the provided Join object.

The join clause is constructed by specifying the target table, optional schema, and any associated conditions for the join operation. Conditional logic is applied to determine the join type (e.g., ON or USING) and format the resulting SQL string.

Parameters:

join - the Join object containing the target table information and the list of conditions defining the join relationship

Returns:

Prepared SQL join clause

protected void appendLimitClause(Limit limit,
 StringBuilder sql)
