I am running:

[postgres@polaris pgsql]$ postmaster -V
postmaster (PostgreSQL) 7.1.3
[postgres@polaris pgsql]$

I am using a table with 609398 records made of varchar's, int's, and float's.
I am doing:

pma=> \d stck_dta_tbl_oprtnl
Table    = stck_dta_tbl_oprtnl

Index:    i_stk_date

  EXEC SQL BEGIN DECLARE SECTION;

    char  i_symbol[6];
    int   i_data_date;
    float i_open;
    float i_high;
    float i_low;
    float i_close;
    int   i_volume;
-

-
  EXEC SQL DECLARE stck_info_crsr CURSOR
    FOR SELECT stck_sym, dta_date_num, opn, hi, lw, cls, vol
    FROM stck_dta_tbl_oprtnl;

  EXEC SQL OPEN stck_info_crsr;
-
-
-

EXEC SQL FETCH stck_info_crsr INTO :i_symbol :i_data_date, :i_open, :i_high,
:i_low, :i_close, :i_volume;

when executing the fetch I get:

sqlcaid = SQLCA
sqlabc = 4.642502
sqlcode = 4.642506
sqlca.sqlerrm.sqlerrml = 49
sqlca.sqlerrm.sqlerrmc = Not correctly formatted int type: 29.25 line 500.
sqlerrp = NOT SET
sqlerrd = 4.642502
sqlext =
BEFORE ** A       6 20020102.000000 28.510000 29.340000 28.459999 0
SYMBOL ** 'A      '
D_DATE ** '0'
i_open ** '20020102.000000'
VOLUME ** '0'

The BEFORE, SYMBOL, D_DATE, i_open, VOLUME are from simple printf's.

!!!!! NOTE THE 6 AFTER THE 'A'!!!!!!!! and the fact that I declare
i_symbol to be char i_symbol[6];

NOW I CHANGE THE i_symbol[6] to i_symbol[5], recompile and rerun.

I get this:

sqlcaid = SQLCA
sqlabc = 4.642502
sqlcode = 4.642506
sqlca.sqlerrm.sqlerrml = 49
sqlca.sqlerrm.sqlerrmc = Not correctly formatted int type: 29.25 line 500.
sqlerrp = NOT SET
sqlerrd = 4.642502
sqlext =
BEFORE ** A     5 20020102.000000 28.510000 29.340000 28.459999 0
SYMBOL ** 'A    '
D_DATE ** '5'
i_open ** '20020102.000000'
VOLUME ** '0'

I tried changing the i_symbol[5] to char *i_symbol and got 'A     0';

Apparently postgres is misreading the declaration of i_symbol and
loading part of the declaration into the actual value of the data!!!!

The folks who do embedded stuff need to take a look at this!!!!!!

NOTE: I can read this record perfectly from within psql, so the data
itself is not corrupted.

pma=> fetch 1 in crsr;
stck_sym|  dta_date|dta_date_num|dta_date_dys|  opn|   hi|   lw|  cls|
vol|unk
--------+----------+------------+------------+-----+-----+-----+-----+-------+---

Thanks for your help!
