–1:存储过程返回dataset 的例子:
c# 代码 :通用类
public static int singlestcd(datetime starttime,datetime endtime,int smtp,string jl,string stdcd,string stcdstr, out dataset ds )
{
int ret=0;
ds=null;
oledbconnection constring=new oledbconnection(appraise.constr);
oledbcommand cmd=new oledbcommand(“p_get_stcd_singleappraise_xunqi”,constring);
try
{
oledbdataadapter ada=new oledbdataadapter();
cmd.commandtype=commandtype.storedprocedure;
cmd.parameters.add(“@starttime”, oledbtype.dbtimestamp).value=starttime ;
cmd.parameters.add(“@endtime”, oledbtype.dbtimestamp).value=endtime ;
cmd.parameters.add(“@smtp”, oledbtype.integer).value=smtp ;
cmd.parameters.add(“@jl”, oledbtype.varchar, 50).value=jl ;
//cmd.parameters.add(“@stdcd”, oledbtype.varchar, 50).value=stdcd ; //评价标准
cmd.parameters.add(“@stcdstr”, oledbtype.varchar, 8000).value=stcdstr ;
system.data.dataset data = new dataset();
ada.selectcommand = cmd;
ada.fill(data,”table”);
ds = data;
ret=ds.tables[0].rows.count;
if ( ret ==-1 )
{
return -1000; //无数据
}
else
{
return ret;
}
}
catch(exception e)
{
//数据库操作发生错误,返回错误代码
system.diagnostics.debug.writeline(e.message);
return -1001;
}
finally
{
constring.close();
cmd.parameters.clear();
}
vb.net 调用:
private sub bindingdatagrid_query()
dim ds as system.data.dataset
zehua.water.appraise.singlestcd(“1999-5-1”, “1999-9-1”, 1, “ⅲ”, “”, “50181300,50185050,50181350,50185100,50185150,50185200,50185250,50181200,50185150,51282300”, ds)
datagrid_query.datasource = ds
datagrid_query.databind()
end sub
–1:存储过程返回数组字符串
rem 执行存储过程,返回一数组
public shared function executesp_toarrary(byval sconnstring as string, byval text_stcd as string, byval text_time as string, byref tableinfo() as string)
dim conn as oledbconnection = new oledbconnection(sconnstring)
redim tableinfo(2)
try
conn.open()
dim command as oledbcommand = new oledbcommand(“p_get_queryvalue”, conn)
command.commandtype = commandtype.storedprocedure
dim sqlparams() as oledbparameter = {new oledbparameter(“@stcd”, text_stcd), new oledbparameter(“@getm”, text_time), new oledbparameter(“@returnvalue”, oledbtype.varchar, 8000), new oledbparameter(“@returncolumncode”, oledbtype.varchar, 8000), new oledbparameter(“@returncolumnname”, oledbtype.varchar, 8000)}
sqlparams(2).direction = parameterdirection.output
sqlparams(3).direction = parameterdirection.output
sqlparams(4).direction = parameterdirection.output
dim i as integer = 0
while i < sqlparams.length
command.parameters.add(sqlparams(i))
i += 1
end while
command.executenonquery()
if sqlparams(2).value.tostring().length > 0 then
tableinfo(0) = sqlparams(2).value.tostring()
else
end if
if sqlparams(3).value.tostring().length > 0 then
tableinfo(1) = sqlparams(3).value.tostring()
else
end if
if sqlparams(4).value.tostring().length > 0 then
tableinfo(2) = sqlparams(4).value.tostring()
else
end if
catch ex as exception
zehua.log.exnotebugs(ex, “siglestcdedit.aspx”) sb.append(ex.message)
finally
conn.close()
end try
end function
