Informix Error Code -517 The total size of the index is too large or too many parts in index.
All database servers have limits on the number of columns that can be included in an index and on the total number of bytes in a key (the sum of the widths of the columns). This CREATE INDEX statement would exceed that limit for this database server. INFORMIX-Universal Server allows 16 key parts (columnar or functional) and a width of 390 bytes.
Informix Error Code -517 The total size of the index is too large or too many parts in index.
All database servers have limits on the number of columns that can be included in an index and on the total number of bytes in a key (the sum of the widths of the columns). This CREATE INDEX statement would exceed that limit for this database server. All database servers support at least 8 columns and a width of 126 bytes. Database servers other than INFORMIX-SE allow 16 and 255 columns, respectively.

Informix Error Code -518 Child constraint constraint-name not found.
If this internal error recurs, please note all circumstances and contact Informix Technical Support.
Informix Error Code -519 Cannot update column to illegal value.
One of the values in this UPDATE statement is based on an expression that is in error. Check each expression in the SET clause for validity. Look in particular at uses of built-in functions such as LENGTH and DATE.
Informix Error Code -520 Cannot open database tblspace.
The database server cannot locate the disk partition in which it has stored a table that is referenced in this command. Contact the database server administrator to find out what the problem is. Possibly the chunk that contains this tblspace has been taken off-line.

Informix Error Code -521 Cannot lock system catalog table-name.
You cannot lock any of the tables that comprise the system catalog. All users need them at all times. The database server handles concurrent access to them correctly, so simply remove this statement from your program.
Informix Error Code -522 Table table-name not selected in query.
You used a correlation name to qualify a column name in either a GROUP BY clause or a SET clause. Consider rewriting the statement in a stored procedure that you then use as the triggered action, passing the column value as an argument. In any case, you must rewrite the statement without a using a correlation name in the GROUP BY clause or the SET clause.
