This is the default output of BTEQ suitable for reports. I will read the first row from the table, I need to execute the content in col1 and col2 of row 1 and store it in to another table.
Designates a maximum error severity level beyond which BTEQ terminates job processing. Specifies a character or character string to represent null field values returned from the Teradata Database.
Thank you for sharing valuable information. Any way I can do this in Bteq script other than using shell scripting. Splits fold each line of a report into two or more lines. For the commands not listed below, refer to the tables above. terafata
Host computer systems rarely have the built-in capability to recognize or handle NULL data. Skips over all intervening BTEQ commands and SQL statements until a specified label is encountered, then resumes processing in sequence. The sample script I have takes over 4 hours to run from the mainframe, but the explain statement said it should run in 30 minutes, plus recommended collecting statistics.
You can also pick the format you desire ranging.

Sign up using Email and Password. If i remove the column name manually and run ,then second export stmt is printing as below,need to eliminate the column heading from it.
Beth 8, 1 16 We have a bunch of JCL on our mainframe including references to BTEQ scripts and I’m wondering if it would kn more sense to import the code in the scripts stored on the mainfraime to new procedures on Teradata.
Specifies a header to appear at the top of every page of a report. Teju Teju 29 November at Assigns severity levels to errors.
Converting from BTEQ on mainframe to Teradata procedure – Stack Overflow
Noticeably, Trradata supports the conditional logic i. I’m thinking if the contents of the scripts were converted to procedures using an automated process, Tdata could compile the script and not have to parse the SQL from the mainframe so executing the code would be easier to execute on the Tdata server.
Email Required, but never shown. Asts Training 14 July at Yet, BTEQ is not a utility designed for bulk data movement. Position summary titles to the left of the summary lines in a report. Here is what is excellent about BTEQ: This has to be continued till the last row in my table.
Limits BTEQ output to errors and request processing statistics. My requirement is I need to write a bteq script which reads row by row from this table until the last row, and execute the row content. What about executing the table content? Data can be read from a file on either a mainframe or LAN attached. Pauses BTEQ processing for a specified period of time.
Teradata – BTEQ
BTEQ operates in two modes: Therefore, in bulk exporting and loading scenarios, Teradata FastExport and MultiLoad are better performers than BTEQ because they are optimized to apply multiple rows in block-level operations. BTEQ limits the record size for exported files to approximately 64K for workstation builds and for mainframe builds.
However, for tables that have more than a few thousand rows It dependsFastExport and MultiLoad are recommended for better efficiency. A data warehouse is a relational database that is designed for query a I would expect code run in a persistent object on the server would perform better than code passed through an external source, but I’m not an expert on Tdata’s optimizations on their procedures.
Export the output of the table in such a format that it beomces executable script and then call that script. This feature means that if a FastExport or MultiLoad job should be interrupted for some reason, it can be restarted again from the last checkpoint, without having to start the job from the beginning.
BTEQ outputs a report format, where Queryman outputs data in a format more like a. Ejects a page whenever the value for one or more specified columns changes.
