It's hard to tell by your example what it is you're trying to accomplish since
the Oracle syntax is incorrect. The substr syntax should be in the form of
substr(<somestring>, start_position, length). The start position can be expressed
using an instr function, and the length can be expressed as the difference of
two instr functions. Postgre makes this type of string parsing much easier using
the split_part function -



select split_part(TRANSPARENTDATA,';',5) from yourtable

which will return the substring '87' (the 5th element in the string separated
into substring elements by the semi-colon).
