Database String Limitations

Does anybody know what the string limitations are for the Database functions?

What I really need to know is the maximum string allowed for DatabaseQuery() and GetDatabaseString()

Thanks.

it should be the internal PB string buffer size (which is 64000 bytes by default but can be changed, check the trick and tips).

Just to save you some time :

Code: Select all

Procedure SetStringManipulationBufferSize(size); - Set the String-Buffer-Size
  
  PBStringBase.l = 0 
  PBMemoryBase.l = 0 
  
  !MOV eax, dword [PB_StringBase] 
  !MOV [esp+4],eax 
  !MOV eax, dword [PB_MemoryBase] 
  !MOV [esp+8],eax 
  
  HeapReAlloc_(PBMemoryBase, #GMEM_ZEROINIT, PBStringBase, size) 
  
  !MOV dword [_PB_StringBase],eax 
  
EndProcedure
