MySQL statement--string multiple substitution, 7th row weight

Multiple substitution of strings: (replaced four times)

SELECT
Replace (replace (replace (
T5,
Substring
T5,
LOCATE (' &timestamp ', T5),
24
),
‘‘
), SUBSTRING (
T5,
LOCATE (' &accesssignature ', T5),
47
), "), SUBSTRING (
T5,
LOCATE (' &time_stamp ', T5),
25
), "), SUBSTRING (
T5,locate (' &access_signature ', T5),
48
),‘‘)
As Temp
From
V2-api-log

Replace (column, the string to be replaced, the string to be replaced)

7th Row Weight:

CREATE TABLE new_table (
SELECT
t1.*
From
tmp_table T1
JOIN tmp_table t2 on t1.temp = t2.temp
and T1. T1 = t2. T1
and T1. T6! = t2. T6
WHERE
ABS (Date (T1.DAYTEMP)-date (t2.daytemp)) <= 7
GROUP by T1. T5)

The demand is the row weight, after the time according to two duplicate data whether within 7th, if within 7th even if repeat, if not in the count.

The idea is a table when two tables are associated with a query
