79 | // This is a generic lookup constructor that will work with any table and any column. | |
80 | // It extends the capabilites of the lookup dialog in the following ways: | |
81 | // | |
82 | // 1) 2 columns rather than one | |
83 | // 2) The ability to select DISTINCT column values | |
84 | // | |
85 | // Only set distinctValues equal to true if necessary. In many cases, the constraints | |
86 | // of the index(es) will enforce this uniqueness. Selecting DISTINCT does require | |
87 | // overhead by the database to ensure that all values returned are distinct. Therefore, | |
88 | // use this ONLY when you need it. | |
89 | // | |
90 | // For complicated queries, you can pass in the sql select statement. This would be | |
91 | // necessary if joins are involved since by default both columns must come from the | |
92 | // same table. | |
93 | // | |
94 | // If you do query by sql statement, you must pass in the maximum length of column1, | |
95 | // since it cannot be derived when you query using your own sql statement. | |
96 | // | |
97 | // The optional database connection can be used if you'd like the lookup class | |
98 | // to use a database pointer other than the global READONLY_DB. This is necessary if | |
99 | // records are being saved, but not committed to the db, yet should be included | |
100 | // in the lookup window. | |
