SAMPLEID is an extension for SAMPLE to get multiple set of sample in single query. Example. SELECT Empid, SAMPLEID FROM TERADATAPOINT.EMPLOYEE SAMPLE 4,4,4 ORDER BY 2,1; *** Query completed. 10 rows found. 2 columns returned. *** Warning: 7473 Requested sample is larger than table rows. All rows returned *** Total elapsed time was 1 second A ? works in Teradata SQL Assistant. It will ask you to enter the parameter: select ?x from ?y; When you run it, SQL Assistant will ask you for the parameters x and y. If you put 10 instances of ?x in your code, SQL Assistant will only ask for x once Hi Parteek, You need to put your SQL code inside Bteq as said by Ulrich. BTEQ is a Teradata sql processing tool, if you need further information about Bteq, do let me know. if you have an idea of Bteq then put your code in Bteq and use some job schedular to automate the Bteq script calls . For example, the below query when run would ask for MSISDN as input on runtime. select * from CUSTOMER_MSISDN where MSISDN = '@inputMSISDN Indentation. When you press the Enter key, the new line might automatically indent to the same level as the line above. This is controlled by the Indent new lines like previous option on the Code Editor tab of the Options screen.. If you highlight one or more lines in the query and press the Tab key, those lines are indented one level. If you press Shift+Tab, the highlighted lines are.

I'm using SAS Enterprise Guide to write some programs/data queries. I don't have permissions to modify the underlying data, which is stored in 'Teradata'. My basic problem is writing efficient SQL queries in this environment. For example, I query a large table (with tens of millions of records) for a small subset of ID's Teradata join syntax is similar to other database SQL joins. You can execute SQL queries with different join types on Teradata machine with little or without any change. There are many advantages of using SQL joins, for example, combine columns from multiples tables, update tables using joins Most DBMSes (including Teradata) don't support table names passed as a variable outside of Dynamic SQL. If you're using SQL Assistant you can simply run select * from ?tablename where my_id = ?id as-is and it will prompt for both variables. - dnoeth Aug 27 '14 at 20:5
SELECT emp_no, first_name, last_name, COALESCE (ph_no1,home_no,ph_no2,'Phone# not available') AS Phone_No FROM teradatapoint.employee; The above query will search for ph_no1 first.

I did some research and could not find a good Teradata SQL formatter. There is a 'Formatter' button in SQL assistant, but the output is a bit ugly. I wrote a small tool with lex & yacc which is able to format a Teradata query. I will distribute this tool if anybody is interested.

They may contain only procedural statements. The definition of stored procedure i Once the above query is executed, it produces the following output and you can see the inserted row in Salary table 2. SAMPLE also operates on the evaluated output. Hence, it does not improve query processing time. My inference: Comparing TOP and SAMPLE, as both execute the query completely, it is better to use TOP(without order by) because we will not provide the system an overhead of getting proportional output from each amp Queries below return database version information. Query SELECT InfoData AS Version FROM DBC.DBCInfoV WHERE InfoKey = 'VERSION'; Columns. Version - version of Teradata Database; Rows. Query returns one row with Teradata Database version. Sample result Teradata CAST Function Examples. The CAST function will convert the type of a table column or an expression to another compatible data type. For example, consider the examples on usage of CAST function: select cast('123456' as INT) as col1; col1 123456. The result be the converted value. However, function will return null if it fails to cast type

The same extended characters will be converted to using Teradata TPT UTF8, and the records can be written into database. Informatica's implementation for Teradata ODBC has problem in UTF16 mode, please be very cautious. BTEQ Example. Let's see a few unicode characters, some of them are BMP, some of them are non-BMP BTEQ is similar to Teradata SQL Assistant in submitting queries to the Teradata Database and generating reports. Yet, they are different in the following aspects: BTEQ connects to the database by means of CLIv2 (Call-Level Interface Version 2), whereas SQL Assistant does so by means of ODBC Another way to see some quick sample data in the table is to use the TOP function, and just select the top several rows from a table. This shows you the field names as well as the values that are in it for just the top rows on one amp (so it's a fast queryfaster than using SAMPLE). sel TOP 10 * from mytable Situation - For example you have a list of account numbers on your Personal Computer or Local Machine which you want to use to retrieve rows from a table, say Account Details, present in Teradata Database.

I have a query that needs to have some data temporarily stored in a table. The table is only needed during the query and could be dropped afterward. There's an easy way to create temp tables in Teradata, but I don't know the syntax If path filtering is desired against tables that have been loaded into S3 with an ORDER BY clause, the recommendation is for the SQL query syntax to include syntax such as the following. This example assumes that the user only wants to access rows that contain the single L_Shipdate value of '1994-01-15' LOGON − Used to log into Teradata system. ACTIVITYCOUNT − Returns the number of rows affected by the previous query. ERRORCODE − Returns the status code of the previous query. DATABASE − Sets the default database. LABEL − Assigns a label to a set of SQL commands. RUN FILE − Executes the query contained in a file The Teradata database provides the ability to limit the number of rows returned from a query starting at the beginning of the results using the top keyword. Listed below are examples of limiting rows with the Teradata database
Teradata has a few interesting features when creating tables. Take a look. We have format and default clauses specified in this table definition. DEFAULT is a standard clause and does what you would expect. The FORMAT only works when one uses Teradata BTEQ tool as opposed to a Teradata SQL Assistant. returns this: In Teradata SQL Assistant The table is automatically discarded once the query is done. Spooled rows, which populate the table, are also discarded when query finishes; It is incorporated into SQL query syntax; There is no data dictionary involvement ; Below is the example for Derived tables. SELECT T.PROD_ID, T.SUM_SALES, RANK(T.SUM_SALES Teradata SQL Assistant/Web Edition is a web-based query tool that allows you to compose queries, submit them to the Teradata Database, and then view the results in a web browser. Overview: Teradata SQL Assistant for Microsoft Windows, originally called Queryman (before V. 6.0)or QueryMan (V. 6.0 and up), is also known as SQLA among.
* OK, in Teradata this means: only requires that the matchable records from both tables must be on the same AMP. This implies the small table to be duplicated to all AMPs. Merge join example. from A join B on A.customer_id = B.customer_id and A.trx_dt between B.eff_dt and B.exp_dt. Customer_id clause is in AND condition with the other · That's not the correct syntax for the Teradata substring function.I suspect you are using ODBC (e.g. SQL Assistant) and allowing it to parse the query.When you put the function in the SELECT list the driver can do the processing on the client side and make it appear to be OK, but it can't do that in a WHERE clause.You need to either use. If you are a Visual Studio developer you can download the Visual Studio Tools for Teradata from the Visual Studio Gallery. (Either from the web, or directly from within VS itself using the Tools > Extensions and Updates menu.) However there is no.
example of teradata query : If the query is being run in SQL Assistant, then this is not proper parameterization as the SQLA will simply replace the value passed in the query For example, C:\Program Files (x86)\Teradata\Client\16.00\Teradata Studio Express.
