# title:        Regression: line/column numbering may be twisted if alias.name syntax is used
# decription:   
#                   NB: it's very _poor_ idea to compare line and column values from text of failed statement
#                   and some concrete values because they depend on position of statement whithin text ('sqltxt')
#                   which we going to execute by ISQL.
#                   Thus it was decided to check only that at final point we will have error log with only ONE
#                   unique pair of values {line, column} - no matter which exactly values are stored there.
#                   For this purpose we run script, filter its log (which contains text like: -At line NN, column MM)
#                   and parse (split) these lines on tokens. We extract tokens with number line and column and add
#                   each pair to the dictionary (Python; Map in java). Name of variable for this dict. = 'pairs'.
#               
#                   Key point: length of this dictionary should be 1.
#                   
#                   Confirmed on 3.0.0.32493 - line and column numbers differed:
#                       -At line 6, column 35
#                       -At line 9, column 5
#                   (thus length of 'pairs' is 2).
#               
#                   On 2.5.6.27001, 4.0.0.145 -- all fine, numbers of line and column is the same, length of 'pairs' = 1.
