Selecting multiple parameters from UDF or procedure

由 主宰稳场 提交于 2020-01-06 23:56:12
问题 I'm trying to compute multiple values and fetch them in a select clause. Whether its computed via UDF or procedure does not matter to me but I can't figure out how to do it in either way. I want to use it like this: SELECT ID, BITMAP(ID) FROM X; which then should return a table with columns ID, Bitset1, Bitset2 . If possible it should be as performant as possible. I have three versions currently (simplified, there's actual more computation): Table UDF CREATE FUNCTION TPCH.BITMAP(IN col BIGINT

How does one handle exceptions in date casting in SAP's HANA?

由 北城以北 提交于 2020-01-05 09:05:33
问题 QUESTION SUMMARY: What is the proper way within HANA SQL or HANA Studio in a view (Calculation, attribute or Analytic) to handle invalid data when attempting to cast to a date so a user can filter the data?

Why anyone stores a date in a decimal field instead of a oh a date/time field is beyond the purview of

sap hana - select top expression

由 删除回忆录丶 提交于 2020-01-04 04:54:11
问题 I have a problem with a stored procedure. The procedure gets as an argument the number of rows needed, but the following does not work in HANA: SELECT TOP :NUM_OF_ROWS * FROM TABLE_NAME I read that TOP in HANA only receives a number, not an expression. Is there another way to do this? My solution for the moment is to select everything and delete the unneeded records on the service, but it's not very efficient. 回答1: Instead of TOP n you can use the LIMIT n option. That one can bind variables.

SQL capped, continuous sum

由 帅比萌擦擦* 提交于 2020-01-01 06:46:53
问题 Assume a time series where we have one value per point in time. I have to calculate a continues sum by calculating the current value + the sum of the previous value. Tricky part however is, that the sum should be capped and hence not exceed a certain value. Example: Sum is capped at +2. +-----+---------+------------+ | row | measure | capped sum | +-----+---------+------------+ | 1 | 1 | 1 | | 2 | 3 | 2 | | 3 | 4 | 2 | | 4 | -2 | 0 | | 5 | 1 | 1 | +-----+---------+------------+ e.g. the

Column store error in HANA

由 随声附和 提交于 2019-12-25 19:40:39
问题 Simple question, does anyone know what this error statement means " SAP DBTech JDBC: [2048]: column store error: search table error: [34086] "? How can it be rectified?. 回答1: This is too little information about the error. Provide more data about what you do and check the indexserver tracefile for a more extensive error message.
