| getSQL | back to summary |
|---|---|
| public String getSQL() Overrides org. Doc from org. For use with CHECK constraints. Under development. Currently supports a subset of expressions and is suitable for CHECK search conditions that refer only to the inserted/updated row. For full DDL reporting of VIEW select queries and CHECK search conditions, future improvements here are dependent upon improvements to SELECT query parsing, so that it is performed in a number of passes. An early pass should result in the query turned into an Expression tree that contains the information in the original SQL without any alterations, and with tables and columns all resolved. This Expression can then be preserved for future use. Table and column names that are not user-defined aliases should be kept as the HsqlName structures so that table or column renaming is reflected in the precompiled query. | |
