Unfortunately I ended up appending rubbish records (entered float in a column which was meant to be Char). How can I delete these selected rubbish records which don't belong? Here is how my table looks like: ...And I want to delete those numeric records (from column " COLMN ") I planned to achieve this

SEL FROM ( SEL SUM(CASE WHEN COALESCE(act.equ_gender1,'') = COALESCE(inact.equ_gender1,'') THEN 0 ELSE 1 END ) AS equ_gender1_chg_cnt, SUM(CASE WHEN COALESCE(act.exp_ex_bmyr1,'') = COALESCE(inact.exp_ex_bmyr1,'') THEN 0

问题 I'm trying to convert a column from char (8) to integer in order to make a referential integrity with an integer. IT didn't work and I test a select in order to check the cast. Utente_cd is a char (8) column SEL CAST(UTENTE_CD AS INTEGER) FROM TABLEA Teradata produces this error: SELECT Failed. 2621: Bad character in format or data of TABLEA. Sometime the char column contains also an alphanumeric code that I should discard. 回答1: In TD15.10 you can do TRYCAST(UTENTE_CD AS INTEGER) which will

问题 I'm trying to figure out the cleanest way to do a comparison in Teradata SQL Assistant. I have the scheduled start date (TimeStamp), the Schedule start time (varchar), actual start and end times (TimeStamp). I need to consolidate the scheduled start date and time and be able to compare it to the actual start and end date and time without modifying the original data (because it's not mine). I realize that the Scheduled Start Time [SST] is in a 24 hour time format with a AM/PM suffix, but like

问题 I have a data set that pulls back visit time in hour/min format (e.g. - 12:33PM would be 1233). I am trying to use the DATEPART function but it keeps giving me a syntax error stating that : "expecting something between '(' and the 'HOUR' keyword. The section below is the piece of the SQL that is giving me errors: CASE WHEN DATEPART(HOUR , VSL.VISIT_TIME) > 12 THEN DATEPART (HOUR, VSL.VISIT_TIME) -12 ELSE DATEPART (HOUR, VSL.VISIT_TIME) END AS THE_TIME I am trying to just get the hour part of

Note that both the values x1,y1 are considered while finding out the closest pair 回答1: A possible solution for your use case would to self-join the table using a NOT EXIST clause to ensure that the record being joined is the closest possible record to

问题 I would like to create a SELECT query that results in a view that is 30 fields long and 1 record thick. 2 records if we're counting the title. The specific part of the larger query in question is: WHERE CAST(EVENT_TIMESTAMP AS DATE) - CONTRACT_EFFECTIVE_DATE = 1 This produces the results desired - records where the days between EVENT_TIMESTAMP and CONTRACT_EFFECTIVE_DATE is 1. But I'd like this for 30 days. Something like: WHERE CAST(EVENT_TIMESTAMP AS DATE) - CONTRACT_EFFECTIVE_DATE = 1:30
