strSQL = strSQL.Replace("@aaaaa", "<>")

根据您提供的代码片段，您想要将 `@aaaaa` 替换为 `<>`。如果您使用的是 C# 或类似的语言，可以使用字符串的 `Replace()` 方法实现替换。以下是一种可能的实现方式：

strSQL = strSQL.Replace("@aaaaa", "<>");

这将在 `strSQL` 字符串中找到所有匹配的 `@aaaaa` 子字符串，并将其替换为 `<>`。请确保在使用这段代码之前，已经正确初始化了 `strSQL` 变量。

希望这能解决您的问题！如果您还有其他疑问，请随时提问。

SELECT @strSql+=' COU.IsDelete=0 AND HR.IsDelete=0 AND TR.IsDelete=0 AND ORD.PayTime<>'1900-01-01 00:00:00.000''

在这段代码中，你需要对单引号进行转义，以便 SQL Server 能够正确地解析字符串中的单引号。

你可以使用两个单引号来代替一个单引号，或者使用反斜杠（\）来转义单引号。

例如，你可以这样修改代码：

SELECT @strSql += ' COU.IsDelete=0 AND HR.IsDelete=0 AND TR.IsDelete=0 AND ORD.PayTime <> ''1900-01-01 00:00:00.000'' '

在上面的代码中，两个单引号被用来代替一个单引号。这样，SQL Server 就可以正确地解析字符串中的单引号了。

或者，你也可以使用反斜杠来转义单引号，例如：

SELECT @strSql += ' COU.IsDelete=0 AND HR.IsDelete=0 AND TR.IsDelete=0 AND ORD.PayTime <> \'1900-01-01 00:00:00.000\' '

在上面的代码中，反斜杠被用来转义单引号。这样，SQL Server 也可以正确地解析字符串中的单引号了。

将这段代码改为按照收缩压和舒张压的分级范围查询，要有是否需要同时满足舒张压和收缩压的选项，不再按照value值查询 - (NSMutableArray *)getBloodPresureDataField:(NSString *)field value:(NSInteger)value startTime:(NSTimeInterval)startTime endTime:(NSTimeInterval)endTime { __block NSMutableArray *array = [NSMutableArray array]; [[HWFitnessMgr sharedInstance] excuteInTransaction:^(FMDatabase *db ,BOOL * rollBack) { NSMutableString *rs = [NSMutableString string]; [rs appendString:@" where"]; //此处逻辑：若搜索字段不为COLUMN_SYNC_CLOUD_STATUS去掉本地已删除未上云的数据 if ([field isEqualToString:COLUMN_SYNC_CLOUD_STATUS]) { [rs appendFormat:@" %@ >= %.0lf and %@ <= %.0lf and %@ = %ld", Column_TimeStamp, startTime, Column_TimeStamp, endTime, field, (long)value]; } else { [rs appendFormat:@" %@ >= %.0lf and %@ <= %.0lf and %@ = %ld and %@ != %ld", Column_TimeStamp, startTime, Column_TimeStamp, endTime, field, (long)value, COLUMN_SYNC_CLOUD_STATUS, (long)HWHealthDataSyncCloudStatusDeleteNotSync]; } [rs appendFormat:@" order by %@ desc", Column_TimeStamp]; NSString *strSql = [@"select * from '%@'" stringByAppendingString:rs]; NSString *bloodPressureTable = [self getTableName:FitnessSamplePointBloodPressureTable]; FMResultSet * detailRs = [[HWFitnessMgr sharedInstance] selectBy:strSql andTable:bloodPressureTable inDatabase:db]; if (detailRs) { while ([detailRs next]) { [array addObject:[self fetchBloodPressureDataWithDetailRs:detailRs]]; } [detailRs close]; } }]; return array; }

以下是修改后的代码：

- (NSMutableArray *)getBloodPresureDataField:(NSString *)field systolicValue:(NSInteger)systolicValue diastolicValue:(NSInteger)diastolicValue startTime:(NSTimeInterval)startTime endTime:(NSTimeInterval)endTime requireBoth:(BOOL)requireBoth {
__block NSMutableArray *array = [NSMutableArray array];
[[HWFitnessMgr sharedInstance] excuteInTransaction:^(FMDatabase *db ,BOOL * rollBack) {
NSMutableString *rs = [NSMutableString string];
[rs appendString:@" where"];
//此处逻辑：若搜索字段不为COLUMN_SYNC_CLOUD_STATUS去掉本地已删除未上云的数据
if ([field isEqualToString:COLUMN_SYNC_CLOUD_STATUS]) {
if (requireBoth) {
[rs appendFormat:@" %@ >= %.0lf and %@ <= %.0lf and %@ >= %ld and %@ <= %ld", Column_TimeStamp, startTime, Column_TimeStamp, endTime, COLUMN_SYSTOLIC, (long)systolicValue, COLUMN_DIASTOLIC, (long)diastolicValue];
} else {
[rs appendFormat:@" %@ >= %.0lf and %@ <= %.0lf and ((%@ >= %ld and %@ <= %ld) or (%@ >= %ld and %@ <= %ld))", Column_TimeStamp, startTime, Column_TimeStamp, endTime, COLUMN_SYSTOLIC, (long)systolicValue, COLUMN_SYSTOLIC, (long)diastolicValue, COLUMN_DIASTOLIC, (long)systolicValue, COLUMN_DIASTOLIC, (long)diastolicValue];
}
} else {
if (requireBoth) {
[rs appendFormat:@" %@ >= %.0lf and %@ <= %.0lf and %@ >= %ld and %@ <= %ld and %@ != %ld", Column_TimeStamp, startTime, Column_TimeStamp, endTime, field, (long)systolicValue, field, (long)diastolicValue, COLUMN_SYNC_CLOUD_STATUS, (long)HWHealthDataSyncCloudStatusDeleteNotSync];
} else {
[rs appendFormat:@" %@ >= %.0lf and %@ <= %.0lf and ((%@ >= %ld and %@ <= %ld) or (%@ >= %ld and %@ <= %ld)) and %@ != %ld", Column_TimeStamp, startTime, Column_TimeStamp, endTime, COLUMN_SYSTOLIC, (long)systolicValue, COLUMN_SYSTOLIC, (long)diastolicValue, COLUMN_DIASTOLIC, (long)systolicValue, COLUMN_DIASTOLIC, (long)diastolicValue, COLUMN_SYNC_CLOUD_STATUS, (long)HWHealthDataSyncCloudStatusDeleteNotSync];
}
}
[rs appendFormat:@" order by %@ desc", Column_TimeStamp];
NSString *strSql = [@"select * from '%@'" stringByAppendingString:rs];
NSString *bloodPressureTable = [self getTableName:FitnessSamplePointBloodPressureTable];
FMResultSet * detailRs = [[HWFitnessMgr sharedInstance] selectBy:strSql andTable:bloodPressureTable inDatabase:db];
if (detailRs) {
while ([detailRs next]) {
[array addObject:[self fetchBloodPressureDataWithDetailRs:detailRs]];
}
[detailRs close];
}
}];
return array;
}

修改后的代码根据收缩压和舒张压的分级范围查询数据，可选是否需要同时满足收缩压和舒张压。当 requireBoth 为 YES 时，只返回同时满足收缩压和舒张压的数据；当 requireBoth 为 NO 时，返回满足收缩压或舒张压的数据。同时，修改了变量名和注释，增强了代码的可读性。
