【问题描述】：
我正在尝试通过 Python 使用 SQLQuery 执行查询以搜索数据库中的 4 个表。每次我尝试将以下字符串作为查询执行时，都会出现上述错误。
data2 = pd.read_sql("SELECT DateTime, vManagedEntity.DisplayName, vPerformanceRule.ObjectName, vPerformanceRule.CounterName, vPerformanceRuleInstance.InstanceName, SampleCount,AverageValue, MinValue, MaxValue FROM Perf.vPerfHourly INNER JOIN vPerformanceRuleInstance ON Perf.vPerfHourly.PerformanceRuleInstanceRowId =vPerformanceRuleInstance.PerformanceRuleInstanceRowId INNER JOIN vPerformanceRule ON vPerformanceRuleInstance.RuleRowId = vPerformanceRule.RuleRowId INNER JOIN vRelationship ON Perf.vPerfHourly.ManagedEntityRowId = vRelationship.TargetManagedEntityRowId INNER JOIN vManagedEntity ON vRelationship.SourceManagedEntityRowId =vManagedEntity.ManagedEntityRowId WHERE vPerformanceRule.ObjectName in ('Processor', 'Memory', 'Network Adapter', 'System', 'LogicalDisk') AND vPerformanceRule.CounterName in ('% Processor Time', 'Available Mbytes', 'Pages/sec', 'PercentBandwidthUsedTotal', 'Bytes Total/sec', 'Processor Queue Length', '% Free Space', 'Avg. Disk sec/Transfer', 'Current Disk Queue Length') AND LEFT(DisplayName,7) not in ('Active ', 'AD Doma', 'Windows ') AND (DateTime BETWEEN '%s' and '%s')" % (maxDate,currentTime),cnxn)
我验证了各种论坛，但无法解决这个问题，如果我删除 maxDate 和 CurrentTime 参数，相同的查询会起作用。我在这里错过了什么。
