First, this is not a question. Also, you need to define your "concat". In usual terminology, "concatenation" is not something which can be applied to columns; it is applied to strings, texts.

Solution 1

Not terribly difficult

SQL

DECLARE @value1 NVARCHAR
DECLARE @value2 NVARCHAR

SELECT @value1 = column FROM table1 WHERE ...
SELECT @value2 = column FROM table2 WHERE ...

INSERT INTO table3(columns) VALUES(@value1 + @value2)

hi there...
is there is any common column in both table, if it is there then it is possible.
first u take columns from both table using join and insert into temp table, and now from temp table u can concat two columns in one column value.

INSERT INTO #ConCatTable(col1_tab1,col2_tab2)
SELECT t1.col1_tab1,t2.col2_tab2 FROM table1 t1 join table2 t2
ONt1.common_colm = t2.comon_colm

SELECT RTRIM(col1_tab1)+'_'+LTRIM(col1_tab2) FROM #ConCatTable
