Hi,
In my application I am passing a date field to the postgres stored
procedure. The problem is when the date field is blank.
My code is like this :
-----------------------------------------------------------------
<TH>Bill Date:</TH>
<TD>
<INPUT TYPE=text NAME="txtBillDate"
VALUE="<? echo $txtBillDate ?>" SIZE=10 MAXLENGTH=10>
</TD>
-----------------------------------------------------------------
I pass the parameters to the stored procedure like this :
-----------------------------------------------------------------
$sSql = "select grn_actions
('FREE','$sYearId','$sUserId',1,1,'$hdnGrnType',
'$txtGrnNumber','$txtGrnDate', '', '', '',
'$txtSupplierCode','$txtBillNumber','$txtBillDate',
'$txtChallanNumber','$ParamStr') as tr_id";
-----------------------------------------------------------------
No if in the above case $txtBillDate is blank, php throws the following
error :
-----------------------------------------------------------------
PostgreSQL query failed: ERROR: Bad date external representation '' in
/home/rajesh/public_html/inv/php/INVGoodsReceiptNoteFreeAddUpd.php on
line 478
-----------------------------------------------------------------
My stored procedure declaration is as below :
-----------------------------------------------------------------
CREATE FUNCTION
grn_actions(varchar,char,char,integer,integer,char,char,date,char,char,char,char,varchar,date,varchar,varchar)
returns char as '
DECLARE
vdocument_type alias for $1;
cyear_id alias for $2;
cuser_id alias for $3;
iform_id alias for $4;
iaction_id alias for $5;
cgrn_type alias for $6;
cgrn_number alias for $7;
dgrn_date alias for $8;
cpurchase_order_year_id alias for $9;
cpurchase_order_type alias for $10;
cpurchase_order_number alias for $11;
csupplier_code alias for $12;
vbill_number alias for $13;
dbill_date alias for $14;
vchallan_number alias for $15;
funcparam_str alias for $16;
-----------------------------------------------------------------
Can anybody tell me how should I pass the date in case it is blank ? The
above field txtBillDate can be blank is certain cases.
Thanks in advance.
Peace
