In td studio by default this feature is deactivated. I kind of started but got stuck in creating and running queries passed as parameters. 1 i have a somewhat large query (~8 tables being joined, 100 lines of sql or so) that i use frequently in order to join many different data sources together.
The following startup parameters can be passed to teradata sql assistant on the command line. This form applies to call, execute, select, insert, update, and delete statements only (with microsoft access, this form is used for insert only.) the parameter markers can only be used in place of data values and must not be enclosed in quotes. You can activate it by clicking the string substitution button of the sql editor view.
A macro is pretty much just a parameterized view, \n\n Parameters that are specified without a name, that is, by using just the question mark alone, display with the name parameter n where the n indicates the index of the parameter for the sql value. There are four types of parameter markers in this case: Works in teradata sql assistant.
If it is used in multiple places within the query, the same value is used in all places. Create a macro in teradata. When using startup parameters, any parameter value that contains spaces must be enclosed in double quotes. But wasn't able to fix that too.
Named parameters function like variables. I was trying to create a simple sql utility that accepts parameters (italics and bold in the list above) and output the remaining fields. (in my case the 9th icon on the top right direct to the sql text). I also tried using parameters as '?dbname' etc to accept values at run time.
Allow use of named parameters in queries this setting allows the use of named parameter substitution in queries. It will ask you to enter the parameter: If you put 10 instances of ?x in your code, sql assistant will only ask for x once. The questionmark is a feature in sql assistant (sqa) to parametrise your sql.
Rules for specifying input and output parameters, call sql statement Enter the value for a named parameter once. I would like to be able to pass a parameter into the query so that myself and other members of my team can work off the same code base and just change the time period that we are looking at. Sqa will ask for the value to replace and then search/replace the parameter.
