Informix Error Messages and Error Codes From Error 542 to 548
Informix Error Code -542 Cannot specify a column more than once in a constraint, trigger, or index.
You name the same column more than once in the triggering column list of an update trigger. Remove the duplicate occurrence of the column name, and try again. This error also will appear if duplicate column names exist in the index list.
-543 ESCAPE character must be only one character.
In the WHERE clause, a subclause ESCAPE char contains more than one character as char. Review the punctuation of the clause, and revise it so that it specifies just one character.
Informix Error Code -544 Cannot have aggregates within aggregates.
The statement contains a call on an aggregate function within the parameter list for another aggregate function, such as SUM(MAX(column)). This action is not supported because all aggregates are calculated over the same groups of rows. If you did not intend an expression of this sort, look for missing or misplaced parentheses. If you did intend it, rethink the query. For example, you might select the MAX values into a temporary table and then take their SUM.
Informix Error Code -545 No write permission for table table-name.
Check the accompanying ISAM error code for more information. With this database server, a database is a directory with the name dbname.dbs, while tables and indexes are files within that directory. You need to have read and write access to all these files in order to exercise normal database functions.
Informix Error Code -546 Cannot have host variables when creating a view view-name.
This statement either prepares or executes a CREATE VIEW statement in which the SELECT statement refers to host variables. This action is not supported. The SELECT statement in a view can be executed from any program and cannot rely on the variables of one program. Review the CREATE VIEW statement, and make sure that it does not contain the names of any host variables, an INTO clause, or a ? placeholder.
Database servers after Version 5.01 do not use this error message.
Informix Error Code -547 Must rollforward database in the directory where the database is.
Before you execute the ROLLFORWARD statement, make the current directory the directory that contains the dbname.dbs directory for the database. Then execute the statement again.
Informix Error Code -548 No referential constraint or trigger allowed on a TEMP table.
You cannot create a constraint or a trigger on a temporary (TEMP) table. Consider creating the temporary table as a permanent table in the database. If this option is feasible, create the table, and then create the trigger on it.
