RE: Dnamic SQL question

 
I am now trying to figure out How to get the VarGraphic data out of SQLDATA. 
I have tried the following, but didn't work out. Any idea what I am missing?


p**---------------------------------------------------------------    
p** getVarGraph                                                       
p**---------------------------------------------------------------    
                                                                      
P getVarGraph     B                                                   
D getVarGraph     PI           256A                                   
                                                                      
d wChar           s            256A                                   
d wLen            s              3S 0                                 
d VarGraph        s            256C   based(ptr1) varying             
                                                                      
c                   eval      ptr1=SQLDATA+2                          
c                   eval      wLen=%len(VarGraph)                     
c                   eval      wChar=%char(%subst(VarGraph:1:wLen))    
c                   return    wChar                                   
                                                                      
p getVarGraph     E

Ali,

Again from memory, and unlucky for you, it is weekend.

SQLDA contains an array, each element reference a field in the  result set.

With the API I use I have to use a pointer to a variable where the value of the 
field will be stored. Hence, I created an array,  apptly called ResultSet and 
have a subfield for each data type available defined, like

Resultset                DS                              DIM(xx)
    CharValue                                  32
    PackValue                                 30 P  9
    ZonedValue                                30 P  9
 etc..

In the SQLDA I put a %adr(Charvalue(SQLIx)), based on the data type of the 
column in the resultset which I have described with the Describe function.

I do not think SQLDA for the API is different for embedded SQL.

I hope this will help (a little).
