SQL queries in JBase

-
The query Language of Jbase is really restrictive. Data analysis and comparison between two table is not possible without the use of spreadsheet software. I recently came to know that Jbase is providing a command called SQLSELECT through which you can actually issue SQL query command directly on Jbase tables.

A sample would be like

SQLSELECT * FROM FBNK.ACCOUNT WHERE SHORT_NAME LIKE '%PETER%' AND CATEGORY = 6601

Limitations:

The command though have serious limitations such as 

The table you query should not have dot charecter for example you cannot query FBNK.CUSTOMER.ACCOUNT with this command.

But there is a workaround for the above drawback. Make a copy of the VOC record FBNK.CUSTOMER.ACCOUNT into a new one without ID in its ID.

For Example:

COPY FROM VOC FBNK.CUSTOMER.ACCOUNT,FBNK.CUSACC

SQLSELECT * FROM FBNK.CUSACC; will work.

The field name should not have dot character. You can overcome this by changing the dot character to underscore. For example SHORT_NAME in the above query.

And so many other limitations such as complexity in executing join operations on tables.

    You can use quotes in your string:

    SQLSELECT CUSTOMER_CODE FROM "FBNK.CUSTOMER.ACCOUNT"

Current Variables in T24

CURRENT VARIABLE Introduction In addition to the system common variables that can be used in ENQUIRY and VERSION there is a feature where the user can populate a variable of their own and use it later. There are now a series of new system variables and a much wider option for users to create and use their own which are: CURRENT.CUSTOMER CURRENT.ARRANGEMENT CURRENT.EXTERNAL.USER These may be set on login by an external user and cleared when they logout. This means that ENQUIRY & VERSION can be tailored to accept the content of the variable instead of forcing a user to enter their own customer number or arrangement etc. Similarly in VERSION you can now default a field content by using the !CURRENT.CUSTOMER to populate a customer field with the current content of the variable. So the variable could be set in one Enquiry and used in either another Enquiry linked to it; or via VERSION to populate fields in an application triggered from the Enquiry. Note: ...
