在SQL Server中将包含空(0x00)字符的二进制数据转换为ASCII

DECLARE @binaryData VARBINARY(MAX);
SET @binaryData = 0x00010203;

-- 将空字符与二进制数据拼接
DECLARE @concatenatedData VARCHAR(MAX);
SET @concatenatedData = CHAR(0x41) + CONVERT(VARCHAR(MAX), @binaryData);

-- 获取拼接后的字符的ASCII码
DECLARE @asciiCode INT;
SET @asciiCode = ASCII(SUBSTRING(@concatenatedData, 2, 1));

SELECT @asciiCode;

DECLARE @binaryData VARBINARY(MAX);
SET @binaryData = 0x00010203;

-- 将空字符与二进制数据拼接
DECLARE @concatenatedData VARCHAR(MAX);
SET @concatenatedData = CHAR(0x41) + CONVERT(VARCHAR(MAX), @binaryData);

-- 将拼接后的字符型数据转换为ASCII码
DECLARE @asciiCode INT;
SET @asciiCode = CONVERT(INT, @concatenatedData);

SELECT @asciiCode;
