Question

Does anybody know, if there is a command string size limitation in Firebird?

When executing a small “insert” script it works perfectly, but when the script has a lot of lines it returns the following errer: "Unexpected end of command - line X, column Y".

Interessting, the line and column number varies dependanding on the actual script size.

I’m using Firebird 2.5

Here is the executing script:

set term ^ ;
EXECUTE BLOCK AS BEGIN
insert into TABLE (COLUMNA) values (13);
...
insert into TABLE (COLUMNA) values (14);
END^
set term ; ^

Answer 1

Firebird 2.5 and earlier have a limitation of 64 kilobytes for the query text, for Firebird 3.0 this limit was increased to 10 MB when the new API is used. An EXECUTE BLOCK is one query, so it should not exceed 64 kilobyte.
