sql server - Query SQL update column image -



sql server - Query SQL update column image -

i'm testing next query update columns in sql server database, reporting next code:

data1 = textbox data2 = textbox2 using ms new memorystream () directcast (picturebox1.image, botmap) .save (ms currentformat) image = ms.toarray () end using dim param sqlparameter () = _ new sqlparameter () {new sqlparameter ("@ data1", _ data1), new sqlparameter ("@ data2", data2), new sqlparameter ("@ image", image)} mcmd.commandtext = "update set table column1 = '" + data1 + "', column2 '" + data1 + "'" mcmd.parameters.add ("@ image", sqldbtype.varbinary, 8000) .value = image

the line of code updates values ​​data1 , data2 image not updated

how can prepare this?

look @ update statement below; doesn't looks right @ syntactically, , missing = after column2

mcmd.commandtext = "update set table column1 = '" + data1 + "', column2 '" + data1 + "'"

it should be

mcmd.commandtext = "update table_name set column1 = '" + data1 + "', column2 = '" + data2 + "'"

also, have declared parameters values, utilize them in update statement

mcmd.commandtext = "update table_name set column1 = @data1, column2 = @data2
