How to select specific data between Quotes (")

问题

I am reposting my question as I am new to SQL 2012.

I want to fetch the numeric data between quotes (") in the following rows,

row1:'asdalknd,"1,2,3,4",slknsdl,"5,6,7,8",snlsn'

row2:'asknd,"111,267,387,4756",snsdl,"534,646,767,348",snlssdsdsdsjkvkn'

row3'....

row4'....

row5'....

row6'...

row7'...

row8'....

The above mentioned are the rows of a single column.

I just want to extract the numerics(may be in another column for each rows)

Can anybody pls help, as this is way above my basic knowledge of t-sql.

Thanks

回答1:

this is Ugly, but will eventually work:

COLUMN = 'jksjdksls#$#$@@kskjfjf,"123,456,789" lsnslkdswfnslsjfls'

left( right(COLUMN,len(COLUMN)-instr(COLUMN,"""")), instr( right(COLUMN,len(COLUMN)-instr(COLUMN,"""")), """") -1 )

--> 123,456,789

This is what is done:

• We take this string 'jksjdksls#$#$@@kskjfjf,"123,456,789" lsnslkdswfnslsjfls'
• find the first occurence of " with instr(COLUMN,"""") --> returns 24
• take the right end of the string with. Therefore we need to take the length of the string with len(COLUMN)--> 55 and substract the position of the first " (24)
• then we need to find the second " with instr()in the right string, which we need to create again with right(COLUMN,len(COLUMN)-instr(COLUMN,"""")) and substract 1 for the ".
