SELECT * FROM OPENQUERY(DB2LinkedServerName, ‘SELECT * FROM WHERE is NULL OR > ””’) And since it only returns valid SQL dates, SQL Server doesn’t blow up when the results come back. Since the query runs on the DB2 server, it doesn’t explode. When it runs, it passes the text of the query to the linked server and the linked server processes it. This allows you to create a WHERE clause that excludes (or transforms if you want) dates that occur before.

OMEGAMON PE Spreadsheet input Data Generator can be used for this as well. The OPENQUERY method accepts two parameters, the name of a linked server, and a string containing the query you want to run. If these storage allocations meet in the middle, then DB2 will enter storage. So, how the heck do you get around it? Fortunately, you have an option in the OPENQUERY method. When DB2 passes to SQL Server, guess what you end up with? That’s right, Error converting data type DBTYPE_DBTIMESTAMP to datetime. SQL Server uses an 8 byte date value (don’t quote me on that), so the furthest back it goes is, about 1500 years short of. Anyway, is a perfectly valid date for DB2 because it uses a 10 byte date value. It defines three key:value pairs using the ID. select jsonobject ('id' value id, 'name' value lastname, 'office' value officenumber) from empdata This example uses the JSONOBJECT scalar function to generate a JSON object. I don’t know what happened on, but I know it was nothing relevant to what was in the database. Let's start with a simple example to see how easy it is to generate a basic JSON object. What had happened was someone botched a date (actually a few dates), accidentally entering instead of. If you exlude a particular column in your SQL Query, SQL Server STILL has to deal with the column because it’s pulling it back from the linked server. It then brings it back to SQL Server for processing. When you run a query against a linked server, SQL apparently goes out to the linked server and gets all of the data. What the heck? How can SQL Server be having an issue with a field that it’s not getting? Without going into all the detail, here’s what I found out. The GENERATED BY DEFAULT AS IDENTITY clause marks the storeid column as an identity column so that when you insert a new row into the stores table, Db2 will automatically generate a sequential integer for the storeid column.

To temporarily get around the issue, I decided to exlude all of the date fields from the query so SQL Server wouldn’t choke. Code language: SQL (Structured Query Language) (sql) In this stores table. I quickly learned that DB2 called the date fields TIMESTAMPS, which I find bizzare since it means something different in SQL Server, but that’s another story. I figured there was some issue with one of the TIMESTAMP fields in the table. While running a query to import data, I kept running into this particular exception:Įrror converting data type DBTYPE_DBTIMESTAMP to datetime Moving data from DB2 to SQL Server has been an experience and a half, fraught with lessons throughout.
