参数化异常 UseGenerateCommandParameterWithLambda(true)

demo 代码 【PostgreSQLCodeFirstTest】

 [Fact]
public void 参数化有问题()
{

    g.pgsql.Delete<Roles>().Where(s=>true).ExecuteAffrows();
    var roleList = new List<Roles>
    {
        new Roles()
        {
            Name = "默认",
            CompanyId = 0,
            Type=RoleType.ALl
        },
        new Roles()
        {
            Name = "A",
            CompanyId = 1,
            TeamId = 2,
            Type=RoleType.Team
        },
        new Roles()
        {
            Name = "B",
            CompanyId = 1,
            TeamId = 2,
            Type=RoleType.Team
        },
    };

    g.pgsql.Insert(roleList).ExecuteAffrows();

    var defualtRoles = g.pgsql.Select<Roles>()
        .Where(s => s.CompanyId == 0)
        .Where(s=>s.Type==RoleType.ALl);

    var filter = new { CompanyId = 1, TeamId = 2, PageIndex = 1, PageSize = 10 };

    var data = g.pgsql.Select<Roles>()
        .WhereIf(filter.CompanyId > 0, s => s.CompanyId == filter.CompanyId)
        .WhereIf(filter.TeamId > 0, s => s.TeamId == filter.TeamId)
        .UnionAll(defualtRoles)
        .Count(out var _)
        .OrderBy(s => s.CompanyId)
        .OrderBy(s => s.Id)
        .Page(filter.PageIndex, filter.PageSize)
        .ToList<Roles>();

    _testOutputHelper.WriteLine(data.Count.ToString());
}

public class Roles
{
    [Column(IsIdentity = true, IsPrimary = true)] public Int32 Id { get; set; }

    public String Name { get; set; }

    public int CompanyId { get; set; }

    public int TeamId { get; set; }

    public RoleType Type { get; set; }

}
public enum  RoleType
{
    ALl=10,
    Team=20,
    User=30
}

生成的sql

SELECT a."id", a."name", a."companyid", a."teamid", a."type" 
FROM ( SELECT a."id", a."name", a."companyid", a."teamid", a."type" 
    FROM "roles" a 
    WHERE (a."companyid" = @exp_0) AND (a."teamid" = @exp_1) 
    UNION ALL 
    SELECT a."id", a."name", a."companyid", a."teamid", a."type" 
    FROM "roles" a 
    WHERE (a."companyid" = 0) AND (a."type" = @exp_0) ) a 
ORDER BY a."companyid", a."id" 
limit 10

下面的这个sql ，type 不应该参数化， 逻辑也有点问题 FROM "roles" a WHERE (a."companyid" = 0) AND (a."type" = @exp_0) ) a

数据库版本

all

安装的Nuget包

3.2.813

.net framework/. net core？ 及具体版本

net 6

这个问题 有计划 修复吗

开启参数化查询功能后，使用 WithParameters 共享参数化，避免产生相同的参数名称：
