Hi
I am trying to send an SQL command to SQLite database and I an building it using the Format function. Target databse table has lots of fields.
IF I use more then ten % in the first argunt of the Format function and erro appears like this:

error: invalid conversion from `const char*' to `int'
error: initializing argument 1 of `Upp::String Upp::Format(int, const char*,Upp::Value, Upp::Value, Upp::Value,Upp::Value, Upp::Value, Upp::Value, Upp::Value, Upp::Value, Upp::Value, Upp::
Value)'

Example:

This works: strSQL=Format("( ...) %d,'%0.2d-%0.2d-%0.2d','%s',%d,'%s','%0.2d-%0.2d-%0.2d')",1,2008,1,1, "aaa",1,"aaa",2008,1,1);

This doesnt works: strSQL=Format("( ...) %d,'%0.2d-%0.2d-%0.2d','%s',%d,'%s','%0.2d-%0.2d-%0.2d',%d)",1,2008,1,1, "aaa",1,"aaa",2008,1,1,1);

Is that a limitation?

Yes, currently, Format is limited to 10 parameters. Adding more is simple, but slightly increases the size of any linux binary using Format...

You can also use:

String Format(const char *s, const Vector<Value>& v);

- that has no limit at all.

Should I increase the limit?
