Question

When the following mysql query is executed,fields get populated with null instead of the value specified.

INSERT INTO invoices VALUES( 
slNo='2', mrp='3', PplusT='3.375', 
name='Eraser', code='002', qty='15', 
unitPrice='3', rateOfTax='12.5', taxAmt='0.375',
cess='0.004', total='50.625', billNo='10001')

The table schema

slNo            int(11)                                     
mrp             float                                           
PplusT          float                                       
name            varchar(50)                          
code            varchar(10)                          
qty             int(11)                 
unitPrice       float                   
rateOfTax       float                   
taxAmt          float                           
cess            float                       
total           float           
billNo          varchar(10) 

I tried the query using PHP as well as PHPMYADMIN but the result is same.

Please check the manual. Replace VALUES with SET

INSERT INTO invoices
SET slNo=2, mrp=3, PplusT=3.375, 
name='Eraser', code='002', qty=15, 
unitPrice=3, rateOfTax=12.5, taxAmt=0.375,
cess=0.004, total=50.625, billNo='10001'

You must remove the quotes from the values for numeric data types, or it will try to insert them as strings.
