ODBC FetchSchema
« on: July 16, 2021, 03:06:58 AM »
I have added a new function to the ScriptBasic ODBC extension module called FetchSchema. This is an example of getting the schema information from the Sage 100 customer table.

Code: ScriptBasic
  1. IMPORT odbc.sbi
  2.  
  3. dbh = odbc::RealConnect("SAGE100","","")
  4. SQL = "SELECT TOP 1 * FROM AR_Customer"
  5. odbc::Query(dbh, SQL)    
  6. odbc::FetchSchema(dbh, col)
  7. odbc::Close(dbh)
  8.  
  9. FOR x = 0 TO UBOUND(col) STEP 5
  10.   PRINT FORMAT("Column Name: %s, Type: %i, Size: %i, Digits: %i, Nullable: %i\n", col[x], col[x + 1], col[x + 2], col[x + 3], col[x + 4])
  11. NEXT
  12.

This is my first pass at generating a CREATE SQL statement from the FetchSchema array. I still need to do the PRIMARY KEY part.

Code: ScriptBasic
  1. IMPORT odbc.sbi
  2.  
  3. dbh = odbc::RealConnect("SAGE100","","")
  4. odbc::Query(dbh,"SELECT TOP 1 * FROM AR_Customer")
  5. odbc::FetchSchema(dbh,col)
  6.  
  7. create_stmt = "CREATE TABLE AR_Customer(\n"
  8. FOR x = 0 TO UBOUND(col) STEP 5
  9.   create_stmt &= col[x] & " "
  10.   IF col[x + 1] = 3 THEN create_stmt &= "DECIMAL(" & col[x + 2] & "," & col[x + 3] & ") "
  11.   IF col[x + 1] = 12 THEN create_stmt &= "VARCHAR(" & col[x + 2] & ") "
  12.   IF col[x + 1] = 91 THEN create_stmt &= "DATE "
  13.   IF col[x + 4] THEN
  14.     create_stmt &= "NULL,\n"
  15.   ELSE
  16.     create_stmt &= "NOT NULL,\n"
  17.   END IF
  18. NEXT
  19.  
  20. create_stmt = LEFT(create_stmt, LEN(create_stmt) - 2)
  21. create_stmt &= ")"
  22.  
  23. PRINT create_stmt, "\n"
  24.    
  25. odbc::Close(dbh)
  26.  

Output
