Tech Tip: Sample code which logs into an ODBC data source and inserts one row of data
PRODUCT: 4D ODBC | VERSION: 6.5 | PLATFORM: Mac & Win
Published On: November 16, 2001

This tech tip provides two examples of code that demonstrate how to log into an ODBC data source and insert one row of data. The first example uses low-level commands while the second example uses contexts.

- Using Low-level commands

LoginID:=OC Login dialog `Login dialog
$sql:="insert into odbcTable values (?,?,?)" `SQL code with three parameters (??? )
process:=OC Create cursor (LoginID)
$res:=OC Set SQL in Cursor (process;$sql)
$res:=OC Bind parameter (process;1;"[Table1]Field1";1)
$res:=OC Bind parameter (process;2;"[Table1]Field2";1)
$res:=OC Bind parameter (process;3;"[Table1]Field3";1)
$res:=OC Execute cursor (process)
OC LOGOUT (LoginID)


- Using Context

LoginID:=OC `Login dialog
Context_ID:=OC Create context ("odbcTable") `Creates a context to the odbctable
OC ADD TO CONTEXT (Context_ID;"field1";"[Table1]Field1")
OC ADD TO CONTEXT (Context_ID;"field2";"[Table1]Field2")
OC ADD TO CONTEXT (Context_ID;"field3";"[Table1]Field3")
$error1:=OC Activate context (loginID;context_ID)
$error:=OC Insert in context (Context_ID) `creates a new row on the ODBC server
`using 4th Dimension objects that have been specified in context binds
OC DROP CONTEXT (Context_ID)
OC LOGOUT (LoginID)

Note: This Tech Tip assumes that a table named "odbcTable" with three fields already exists on the ODBC Data Source.
