Pervasive v10查询语法错误：原v8可用的含WOBOM_LINE^的查询报错
Alright, let's break down what's happening here. Your query works fine in Pervasive v8 but throws a syntax error in v10 because of that ^ character—here's why and how to fix it:
The Root Cause
In Pervasive v8, the ^ symbol was a non-standard shorthand for the NOT operator. So your line WOBOM_LINE^ = ? was being interpreted as NOT (WOBOM_LINE = ?) (meaning "WOBOM_LINE is not equal to the parameter").
But starting with Pervasive v10, the engine tightened up its SQL parsing to align more with standard SQL. That old non-standard ^ shorthand got dropped, so the database now sees WOBOM_LINE^ as a malformed identifier/operator combo, hence the syntax error.
Fixes You Can Apply
There are two straightforward, compatible fixes here:
1. Use Standard SQL's NOT or <> Operator
Replace the non-standard ^ with either explicit NOT or the standard inequality operator <>—both work in v8 and v10:
Option 1 (explicit NOT):
SELECT WOBOM_ASSY FROM WOBOM WHERE NOT (WOBOM_LINE = ?) AND WOBOM_WOPRE = ? AND WOBOM_WOSUF = ?
Option 2 (shorthand inequality, more common):
SELECT WOBOM_ASSY FROM WOBOM WHERE WOBOM_LINE <> ? AND WOBOM_WOPRE = ? AND WOBOM_WOSUF = ?
2. Double-Check If ^ Is Part of the Field Name (Unlikely, But Possible)
If by chance your actual column name is WOBOM_LINE^ (not a great naming choice, but it happens), you'll need to wrap the column name in double quotes to tell the engine it's a literal identifier:
SELECT WOBOM_ASSY FROM WOBOM WHERE "WOBOM_LINE^" = ? AND WOBOM_WOPRE = ? AND WOBOM_WOSUF = ?
That said, your error message mentions WOBOM_LINE^<>, which points to an operator issue rather than a column name problem—so the first fix is almost certainly what you need.
Quick Note on Pervasive Version Changes
Pervasive has been moving toward standard SQL compliance in newer versions, so a lot of old non-standard shorthands (like this ^ for NOT) get deprecated. Sticking to standard SQL syntax will save you headaches when upgrading in the future.
