numeric fields do not take value with single code
if you know the value is null
then simple pass 0 or Null
eg.
insert into ItemMaster
( ITEM_CODE,
ITEM_NAME,
DRAWING_NO,
WEIGHT_CAST,
WEIGHT_FINISH,
CROSSING_COUNT,
catID )
values('a','a','',0,0,'','')

else you can use

insert into ItemMaster
( ITEM_CODE,
ITEM_NAME,
DRAWING_NO,
WEIGHT_CAST,
WEIGHT_FINISH,
CROSSING_COUNT,
catID )
values('a','a','',Null,Null,'','')

Solution 2

'' is not a NULL value, have a try at the statement below:

SQL

insert into ItemMaster
( ITEM_CODE,
ITEM_NAME,
 DRAWING_NO,
 WEIGHT_CAST,
 WEIGHT_FINISH,
CROSSING_COUNT,
catID )
values('a','a','',null,null,'','')

" ITEM_CODE," & _
" ITEM_NAME," & _
" DRAWING_NO," & _
" WEIGHT_CAST," & _
" WEIGHT_FINISH," & _
" CROSSING_COUNT," & _

" )" & _
" values(" & _
"'" & Replace(txtItemCode.Text, "'", "''") & "'," & _
"'" & Replace(txtItemName.Text, "'", "''") & "'," & _
"'" & Replace(txtDrawingNo.Text, "'", "''") & "'," & _
"'" & Replace(txtStWeightCst.Text, "'", "''") & "'," & _
IIf((txtStWeightFin.Text.Length=0), "NULL", string.concat("'", Replace(txtStWeightFin.Text, "'", "''") & "',") & _
IIf((txtNoOfCross.Text.Length=0), "NULL", string.concat("'", Replace(txtNoOfCross.Text, "'", "''") & "',") & _
"'" & IIf(cboItemCategoty.SelectedIndex = -1, "", cboItemCategoty.SelectedValue) & "'" & _

Solution 3

Make sure that you are mapping the correct values to the respected columns in the insert statement.

as varchar,nvarchar and date columns will take the values enclosed with single quotes. eg ( 'abc' )
numeric data columns you should pass the default values(0). eg( 1,3)
