dear all,

i have 3 SQL statement i want to merge them into one but each of them has its own where condition how can i merge them
1st:

SELECT
	ProjectCode,
	SUM (- 1 *(CreditAm) +(DebitAm)) AS Balance
FROM
	[dbo].[AcDetail]
WHERE
	AcCode IN (
		401000,
		402000,
		403000,
		404000,
		405000,
		406000,
		407000,
		499999
	)
AND BranchCode = 'WP'
AND TDate >= '2016-01-01'
AND TDate <= '2016-12-31'
GROUP BY
	ProjectCode

2nd

SELECT
	ProjectCode,
	SUM (- 1 *(CreditAm) +(DebitAm)) AS Materials
FROM
	[dbo].[AcDetail]
WHERE
	AcCode IN (600001, 600002, 600151)
AND BranchCode = 'WP'
AND TDate >= '2016-01-01'
AND TDate <= '2016-12-31'
GROUP BY
	ProjectCode

3rd:

SELECT
	ProjectCode,
	SUM (- 1 *(CreditAm) +(DebitAm)) AS Salaries
FROM
	[dbo].[AcDetail]
WHERE
	AcCode IN (
		650001,
		650005,
		650006,
		650007,
		650008,
		650009,
		650010,
		650020,
		650021,
		650022,
		650023,
		650024,
		650025,
		650026,
		650027
	)
AND BranchCode = 'WP'
AND TDate >= '2016-01-01'
AND TDate <= '2016-12-31'
GROUP BY
	ProjectCode
ORDER BY
	ProjectCode

What I have tried:

SELECT
	ProjectCode,
	SUM (- 1 *(CreditAm) +(DebitAm)) AS Balance
FROM
	[dbo].[AcDetail]
WHERE
	AcCode IN (
		401000,
		402000,
		403000,
		404000,
		405000,
		406000,
		407000,
		499999
	)
AND BranchCode = 'WP'
AND TDate >= '2016-01-01'
AND TDate <= '2016-12-31'
GROUP BY
	ProjectCode
