When there is a large amount of comma separated values as the input parameter, the code can be delayed for a few seconds while inserting the data into the temp table. SQL Server SELECT INTO Example As alternate solution we can use is the SELECT…INTO command which generally ...

(这个方法在sqlserver2000的环境下做一般能成功,在sqlserver7及以下版本就不一定了): 第一步: 先备份整个数据库以备不测 第二步: 备份结束后,在Query Analyzer中执行如下的语句: exec sp_detach_db yourDBName,true --卸除这个DB在MSSQL中的注册信息 ...
#temptable table.create = true table.columns.add('a', sql.Int, {nullable: true, primary: true}) table.columns.add('b', sql.VarChar(50), {nullable: false}) table.rows.add(777, 'test') const request = new sql.Request() request.bulk(table, (err, result) => { // ... error ...
The reason is that "Query 4" refers to ##tmpTest table not with a single T-SQL command. It refers to it in each iteration in the while loop. So, when "Query 1" is closed (##tmpTest dropped), SQL Server waits until "Query 4" completes its latest T-SQL statement which refers to...
We have an installation of SQL Server CTP 2.2, "Evaluation", it has expired and the SQL service has stopped. We want to move to a production version of SQL server 2019 but it is not available yet, as far I know. We have tried to upgrade from Evaluation to Developer to get the SQL...
const sql = require('mssql') (async function () { try { let pool = await sql.connect(config) let result1 = await pool.request() .input('input_parameter', sql.Int, value) .query('select * from mytable where id = @input_parameter') console.dir(result1) // Stored procedure let ...
Temp tables may be a better solution in this case. For queries that join the table variable with other tables, use the RECOMPILE hint, which causes the optimizer to use the correct cardinality for the table variable. table variables aren't supported in the SQL Server optimizer's cost-based...
