how to go through table cells

Posted on Aug 23, 2016 at 10:27 AM 27 Views

Hi experts,

In a given table in hana, is it possible to go though cells. My current progress is hampered by the need to specify column names. For example,

SELECT <column name> FROM <table name>;

DECLARE i INT;

DECLARE j INT;

SELECT COUNT(*) INTO j FROM <table name>;

FOR i in 1..j DO

if <table name>. <column name>[i] > 0.05

then .........

END FOR;

But I want to go through all the cells regardless of the columns. Is it possible in hana with static sql?

Thanks

    Hello

    What is your requirement? I'm sure there will be a more elegant solution than iterating over all rows and columns.

      I wouldn't say that their use is inevitable.

      When writing applications to consume HANA data, push as much logic into the database as possible, and then consume the smallest result set in the consumption layer - and here is where you might find programming features to iterate over rows and columns.

    Yes, it is possible with Static SQL

    use this Query:

    Select

    Case

    when clolumn1 > 0.05

    then ...

    else

    end as column1,

    Case

    when clolumn2 > 0.05

    then ...

    else

    end as column2,

    .....

    ....

    ....

    <like wise for all columns>

    From Table.

    Happy HANA 😊
